Welcome back, everyone, to SuperCloud 4's episode four, JVAI, I'm John Roy, Dave Vellante. We've got, wrapping up day one, you've got two closing sessions. First, we're interviewing Howie Shue, Cube alumni. Now, Cube host, as of today, also senior executive at Palo Alto Networks, heading up the AI machine learning team over there. Howie, great to have you back, and congratulations on a great panel. Thank you. It's a lot of fun. It was really good. You were nervous, where you did great.  I did all the homework. You did your homework. The key is the guests, though, right? I mean, the guests, you did a great job asking the question, but having a great guest from Salesforce, Google, and Microsoft, that they're so articulate, and so technically oriented, but can talk in business terms, makes for a great panel. Yeah. So, well done. So, the panel we want to review real quick with you is AI, Enterprise AI, Hyper Reality, did a poll. You had VJ from Microsoft, laid out great commentary there. We had Warren from Google, and Jay Ash from Salesforce, all senior executives. Really interesting perspective. Enterprise sees great hope, but it's here.  It's just, they didn't have co-pilot last year. So, what's your takeaway as looking at now, zooming out and looking at yourself in the panel, what was the big takeaway? Because you had some serious hitters there. Big names, a lot of projects, all legit AI going on and all those companies. So, zoom out a little bit, right? Everyone is asking, hey, this enterprise, software, adoption of the general AI, is that a hype or reality? What is the killer applications? Because we all talk about it, but how many are in production and then are there any killer applications? My one liner takeaway on this one question is, it's really about giving super power to everyone from all walks of life. That's actually pretty amazing, right? Because whether you are doing programmer, product manager, whatever the things you are doing, you are going to get super power and then do something fundamentally quite different on top of what you have been doing. Some of what you have been doing may be replaced by co-pilot, but you are suddenly actually empowered to do a lot more things. That is my one liner takeaway because it's not just the killer applications, it's actually giving super power to everyone. But that's what it was, the killer app was accessed for all, right? To drive productivity. It's interesting in tech and business schools, you hear terms like competitive strategy, competitive advantage. The word that I always love was disruptive enabler. And with the consumerization of AI, what's coming out of day one here, Dave, and how I would say is that you're seeing the consumerization of AI in the hands of people where they go, oh, magic, or I like this, I can feel the benefit, I can see some future, but how your point about that enablement, that's a disruptive enablement because the creativity, even Warren said it on the cute beer, he said he sees more creativity coming, more you say productivity, a room from Intel said knowledge workers. All the same language for enablement. This is like the, this is the key thing, the enablement, what will AI enable? And enablement not just for incrementally better, incrementally productivity, right? It's actually, think out of the box, step-function improvement, right? Something very different. I've been having conversations with some of my friends, they are the, whether the MLE, machine learning engineer, or data scientists in some big companies, right? The boundary between data scientists and then machine learning engineers are kind of getting, the boundary is getting blurry. So you need to rethink about. You don't need to have ADHDs on staff. I heard one of your comments on your panel is interesting.  Imagine having that capability, so that step-function change is interesting. I guess my next question is, where are we in your mind, okay? Enterprise always feel a little bit behind because there's so much to going on, data, governance, security, consumer, that starts just slinging code, trying to launch a company. Then you got the big hyperscalers with the cloud scale out there. How do you see the interplay between, say, the hot startup, you know, throwing the arrows at the big guys, trying to, David versus Goliath, the big whales, and then the, I won't say slow-moving enterprise, but traditionally slow-moving to implement. You know, look, you know, the technology is amazing, right? All of us have the consensus at this point. The question is, can we land this technology so that it can be, you know, useful at scale? And then, you know, people can consume that. I think there's still a long way to go on that one, right? You know, I think Warren mentioned that. We have all the pieces, but when you piece them together, you know, it takes a lot of effort. What I would have called it, I think some of the people, you know, at this super cloud, also mentioned that there is a last mile thing, right? You know, all the technology is good. How do you connect that technology with the data you have?  The domain name may be too expensive to get, right?  You know, all the technology is good. You know, how do I actually attach my data with it, right? Is it easy, right? You know, sure, I have the fine tuning, I have the rag, you know, on the paper, but when you actually do it, there are a lot of details. And also your LinkedIn poll showed 63% said biggest shift but takes time. There were some skeptics, about 20% of the people said, oh, it's peak cycle. But so what is that last mile? What are those last mile? Is it data privacy? Is it data quality? So I did a two poll.  The other one is, what are the number one challenge? It's actually all over the place. There's no one place, right? Well, the model can be better. We all know that, right?  And then there is also a kind of a data side, right? Data could be data retrieval, right? The accuracy or that sort of thing. And then there is a compliance security, governance, right? So. All of the above. All of the above. All of the above. That's the last mile. So the last one mile is not just the one thing. It was the last mile of a number. We got to dig the trench. We have to get the cable. Hold on, hold on. I want to tee into this because Brotton Saha, this AWS VP was on our keynote. He was our opening presentation. You had Google, Microsoft. We had all the hyperscales here in SuperCloud 4, as well as the CTO of SaaS, an older company that has modernized their game. Then we had a panel of founders. I call them the senior founders. I won't say senior, I didn't call them that, but experienced founders. Piyush Sharma and Vikram Yoshi, one's a compute guy, one's a security guy. Both. Serial entrepreneur. Serial entrepreneur.  And you know, you work for the big company.  You've been an EIR at Greylock. So I have to ask you the question I asked those guys. As an experienced founder that's seen the cycles before, I'll see you're well articulated what you're looking at, killer app, infrastructure, game changing, step function. If you were going to start a company today, what would you, how would you do it? Like, I mean, obviously the cloud was great because you didn't have to provision any hardware to get going. So you're in the market quick. What's that feature of AI that makes it better now to do a startup? And what would you do? How would you execute? Not the idea, but like take us through the mindset. If you're going to start a company tomorrow, say take the cube and turn it into it. Right. So the mindset of us, right? There are a number of things, right? You know, we already talked about there are multiple last mile issues, right? I would say solving any one of them is a big deal, right?  So that's sort of the one thing. The other thing is, I think, you know, I mentioned this at a super cloud three, you know, the future of entrepreneur, they are facing a very different environment because of the power, because of the superpower they have, you know, we'll probably, we'll see a lot more solopreneur. Now by solopreneur, I do not mean single, I mean a lot less resources, right? We used to be kind of a 20 people, 30 people team. Today you should think about it, can you do this, you know, with five people? I was actually having lunch with a VJ, you know, today before the panel. And he mentioned that, hey, you know, anyone can start a GNAI project, you know, with real sort of a budget, right? A lifestyle business could pick one little thing in a vertical and be big, and own it. Yeah, my son is doing a GNAI project, he's in the middle school, and then he said, hey, daddy, can I get some budget from you? I said, sure. He's doing great. And I'm asking him, I said, how much? You know, he said, five dollars. Five dollars would give him a long way to do it. He's gonna be a great entrepreneur, you see funding. You often say this industry has solved complexity with complexity, because you think about the cloud, we talked about two pizza teams, right? Two pizza, and then that turned into what you just described as a 20 pizza team. Will the same thing happen here? Because we're saying, okay, you can start these companies for a lot less, right? Do you think that the complexity that we tend to add on to this business is gonna be similar in that we tend to modularize things, we tend to open source, you know, new projects, and it increases complexity? Do you think that will? But then at that point, you're talking about a very different problem, because you know, like any technology, right? Once that one technology becomes the mainstream, right? So I grew up at VMware, right, you know? Just a very small number of people get a first hypervisor out, right? But by the time, you know, I left VMware 10 years later, it was 15,000 people working on that hypervisor. Success. The reason is because then you have a partnership, integration this, you know, sales and the storyline. You're growing your market, yeah. But that's a very different problem. I think, you know, what we are talking about here is, you know, the superpower that Genevieve I brings to the table can do things that otherwise takes five people. Yeah, and I think that's the, my point about complexity, Dave, is that AI can reduce that. I think that's the key. My question on what you were saying earlier about models. Brad and Satya, also, and I talked about at Amazon, and your guests talked about as well, it's not just the models that are important. It's the end-to-end, and you say last mile, so I'm assuming that there's the beginning, middle, and end of the story. So you could have a great model, but if you're too focused on one model and Arun and Intel just said, why build a model that already exists, it means to an end. So my guest panelists actually all talk about this one thing, right? One is technology, the other one is how you look at it, the technology, right? VJ actually mentioned to me, you know, early today during my lunch, he said, hey, and everyone's talking about hallucination being a problem. Sure, it can be a problem sometimes, but look at a hallucination as a feature, right? You know, it's kind of a creativity. So this is, at that point, it's like how you work with the generative AI. You need to rethink about, you know, that it takes a different culture, a different mindset, a different way of thinking. So I was asking my panelists today about, hey, what is the, you know, it will take time. What sort of things will it take time, right? What is the technology built out? But the other thing is actually the way we think about how we are working with this technology will take time. It's not like everyone still thinks of the traditional way, right? Enterprise software. So I think that would take some time. You don't want hallucination, just keep it sober. Feed it data that you know is good, and keep your model clean. Howie, final word, what's your takeaway from SuperCloud 4 this year? If you look back at the conversations you had, how much is we're having here? What's your big takeaway? So this is the fourth episode of this, you know, SuperCloud, I remember a year ago, right? This is about cloud, not AI. And then in SuperCloud 2, you know, I was among one of the smaller people talking about AI, generative AI, right? Last episode, you know, I was more talking about security, but a lot more generative AI.  Can we just call it Super AI day and just kind of get over with it? Super power. Yes, so my takeaway is, you know, this thing is, you know, it's going to be real, and it's going to take time. And unlike the previous generation of the technology wave, it will still take time, but at a compressed timeframe. You're a wonderful contributor. Thank you so much for all the prep work that you did. Organizing the panel was fantastic. And if you need analyst's job, we got some openings for you. I know you got a nice gig over in Palo Alto. We have stock options too. Coins. Cube coins. Cube coins. Howey, great panel, you hosted again. Again, this is what we're going to do more of. Thank you for your contribution, folks watching. People bring their guests to the table, amazing guests, great content. All of SuperCloud's have been about data, and the data is changing now in generative AI. This is the next big thing. It's just early days. It's not even inning one. It's pre-gaining. There's a generational shift happening. It's all about data. It's all about scale and software. The superpowers will be there. We'll be back with the short break after the short break for closing segments. Stay with us.


Winning the PageSpeed Race. Secrets to supercharge your website speed. Okay, let me give you a little brief history first on Google because we're talking about PageSpeed and obviously you're watching this video because you wanna increase your PageSpeed. And I can assure you that by the end of this video you're gonna be able to increase your PageSpeed with a little bit of tweaks and you're gonna rank higher. So let's talk about this. In 2009, Google announced that they wanted to increase PageSpeed, which means the load time. How quick that page actually comes up. So in 2010, Google announced that part of their rankings would be PageSpeed. In other words, the pages that loaded faster would have an SEO advantage over pages that loaded slower. So this is something you have to look at if you wanna rank your web pages. Now, five years later in 2015, Google announced that there were more searches on mobile devices than there were on desktops. And by 2019, that had grown to 61% of all searches are on mobile devices. Now, Google has a thing called Accelerated Mobile Pages which is to encourage people to not only have a responsive website on mobile device and have a desktop but to have accelerated mobile pages in addition to that. Now, I'll throw this up on the screen right now. Although many site owners and SEO complain about having to tend to the PageSpeed and AMP on top of the other 200 plus ranking factors that already give them headaches, PageSpeed is indeed a worthy effort for site owners to focus on. In 2017, Google conducted a study where the results very much justified their focus on making a web faster. They found that as page load time goes from one second to 10 seconds, the probability of a mobile site visitor bouncing increases, get this guys, by 123%. Now, Google even announced a thing called Core Web Vitals. And why is all of this stuff so important nowadays because people's attention span has become so short? So the faster your pages load, the faster they come up on a mobile device, the better off you are because their attention span is so low that they may just leave. So that's why we have to pay attention to this now.  If you wanted to win a car race, what would you do? You would have the lightest, most simple car with the most power and most control and that way you would be faster than all the other cars. And that's how you have to think of your website. It's a car race with your web pages. You don't want complicated pages that do a lot of things and then look real fancy and then have a lot of colors and a lot of stuff moving because that makes your website heavy and that makes it slow and we wanna go fast. Now, I want you to think of it this way. A race car doesn't have cup holders. No, they don't have that. They don't have radios. They don't have sun visors. They don't have any of these things because that does not help them win the race. And it's the same thing with your website. Don't put a lot of stuff on the pages that people are gonna be going to because they don't need that. That's not what they need and it's gonna slow down your website. Now, this would include getting rid of third-party coding on there, optimizing some of your images and not having them at such a high resolution that they take a long time to load. All of these things are gonna help your website. Now, let's talk about making it powerful. I know the main goal of you guys and most of you have websites is to have the cheapest hosting plan possible. Matter of fact, you may have even searched cheapest hosting plan possible.  Why not pay a few dollars more a month and have a dedicated hosting plan so that your website loads incredibly fast? Did you know that a lot of these discount hosting plans cram tens of thousands of websites into one hosting plan which slows everybody down and it leaves you competing for power? You don't want that happening. Now, check out the graphic I'm gonna put on the screen right now. If you wanna race in big leagues, it's time to get a grown-up hosting plan. For WordPress websites, managed hosting companies such as WP Engine and Flywheel utilize servers that are powerful and specifically tuned to serve up WordPress websites faster. If managed WordPress hosting isn't your thing or if you don't have a WordPress website, okay, upgrading to a VPS or virtual private server will result in your website having way more computing resources available to you. You'll also have more control over your own hosting environment, allowing you to tune up your engine with things like the latest versions of PHP, MySQL, varnish, caching and other modern web server technologies. You'll no longer be at the mercy of your shared hosting plan. You can actually do something with your hosting plan. Now, if you wanted to win this race with your race car, what else would you do? You'd probably drive it better, right? You'd cut the corners a little bit more. You'd be a little bit sleeker than the other drivers. That's what you need to do with your website. Think about your navigation. How quickly can somebody navigate your website? Get from one part to the other. This is super important that you have very easy navigation, very easy website to use because even if it loads quickly and all your images come up quick and your page comes up quick, if they have a hard time getting around your website, that's gonna hurt you too. Because if it's hard for them to get around your website, guess what they're gonna do? They're gonna leave. Now, check out the image I'm gonna put on the screen here. This is kinda cool. When a browser loads a webpage, it goes through a process called coincidentally painting. Each page is painted as the browser received bits of data from the webpage source code. This painting process can either be executed efficiently, such as painting walls before refinishing the floors, or it can be done in a more chaotic out-of-order fashion that requires several trips back to the beginning of the process to redo or fix or add something that could've, should've been done in the earlier process. Here's where things can get technical, but it's important to do whatever you can to help the site drive the track more efficiently. Now, let's talk a little bit more about how these pages load. And I wanna put a graphic up on the screen here too. This is how a CDN or content delivery network actually works. Getting back to our race car analogy. Utilizing caching, which actually has all that information ready and available for use, and a CDN equals a much faster trip around the racetrack. Those are two of the basic building blocks of an efficient page painting. And there are even more technologies that can be deployed as well. On WordPress, the following can be implemented via plug-in or plug-ins. Again, WP Rocket and ImagineFi are particularly good combo for achieving a lot of this. Okay, so I wanna talk to you now about core web vitals. Now, keep in mind, I know some of this is kinda technical, but once you educate yourself on this, you can go out and search for somebody to have do some of this work for you on Upwork or on Fiverr or whatever. But if you don't know about it, you don't know what to ask for, you don't even know what they're doing. So educate yourself on what needs to be done. Let's check out this graphic. Okay, so these are pretty technical concepts, but here's a quick overview to get you familiar with what they mean. First off, largest content paint refers to the painting of the largest element on the page. Google's PageSpeed Insights tool will tell you which element is considered to be the LCP element of that page. A lot of times this is a hero image or a large slider area, but it varies from page to page. So run the tool to identify the largest content paint on your page and then think about what you can do to make that particular element faster. Next one I wanna talk to you about is the first input delay, okay? It's the delay between the user's first action and the browser's ability to respond to it. An example of an FID or first input delay issue would be a button that is visible to a user sooner than it becomes clickable. The delay would be caused by the click functionality loading notably later than the button itself. And the last one there is the cumulative layout shift. Okay, so that's called a CLS. It's a set of three big words basically that refer to one simple concept. You know when you're loading a webpage on your phone and you go to click on something or read something, but then it hops up or down because something else loaded above or below it. Okay, we've all had that irritating thing happen. That movement is the CLS. It's majorly annoying and it's a byproduct of an inefficient page painting. Okay, so in conclusion, I want you to categorize your website. Is it a race car? Does it do all these things? Or is it a golf cart? A golf cart. You know, it's funny I live in a neighborhood where a lot of people have golf carts. And it's funny, here's why it's funny that a lot of people in my neighborhood have golf carts and they go up to the community center in the swimming pool and all that. It's funny because we don't have a golf course. No, we don't have a golf course, but we have a lot of people with very high-end golf carts. But the thing with the golf carts, they may be nice, like your website, may be nice, but it's not really doing the job. It's too slow. It's not gonna win any races. So you wanna have the race car type website. It's clean and slick and moves fast and gets people what they want. As opposed to that really tricked out golf cart that's got a lot of horns and bells and vessels and fancy wheels on it and all this. I mean, really, some of these golf carts in my neighborhood are insane.  Is your website the same way? I want you to think about that. Now, I also have a course below. It's a $97 course.

Good evening what who are you I beg your pardon I said who are you what are you doing here my name is Gabriel I am Butler to the Holloway Gabriel but you you can't be well you're you're dead midnight the witching hour when the night is darkest our fears the strongest and our strength that it's lowest ever midnight when the graves gave open and death strikes how you learn the answer in just a minute in the house that time forgot murder at midnight tales of mystery and terror by radius masters of the macabre our story by Sigmund Miller is the house that time forgot early evening on a desolate part of the Virginia coast along a road near the beach comes a car with two people in it I guess we've done enough looking for today even really beautiful country around here dear wild and lovely darling if we can't find a house perhaps we should buy some land and build we better start back to town it's getting dark and I think we're in for a storm look Fred look at that house we're coming to oh isn't it a beauty oh yeah nobody that owns that one would want to sell it drive slowly dear I'd like to take a good look at it all right there's a for sale sign yeah this house for sale see mr. Cecil Smith Westfield Virginia well that's interesting let's drive in there into the grounds I'll we can come back tomorrow it's really starting to blow take a minute I've just got to have a close look all right but we're gonna get caught in the rain back in to save time we'll watch the fenders on that side all right dear I'll watch come ahead my clear okay you're all right fine oh there's a light in one of the gable windows I guess somebody's home grounds look a little neglected though grounds who cares about that go ahead and knock okay I wish they'd hurry we're gonna get caught in a storm don't worry about it they don't seem to answer do they try knocking again so I must be somebody home we saw a light in the window maybe they can't hear us let's try calling them oh hello there hello that's very strange yeah I hear something listen it's a clock striking let's let's try the door it's not locked what do you think well let's go in it's a big place but lovely wait a minute anybody home if there is they can't hear us or don't want to come on we'll come back tomorrow place needs fixing up but it's worth fixing shall we take it we'll see very interested in buying the Holloway house yes mr. smear it's just the kind of house we've been looking for it's a fine place all right even got a private inlet to more a large-sized boat it's got everything except except what's it well it's only fair that I tell you all it's defects what defects mrs. Smith you see mr. Jordan it's kind of hard to put your finger on it there's something very queer about the house you mean it's haunted well I don't know exactly mr. Jordan no one has seen a goose there yet well we we don't mind ghosts do we know no we don't believe it well I didn't say it was haunted but well people say that the house is alive that that it has a life and a wheel of its own a life well I don't know what you mean well I've had four caretakers in the Holloway house since I took possession of it and none of them stayed more than a few days well why did they quit I don't know they didn't see any ghosts or apparitions but they all felt the same way that that the house was alive every one of them well there must have been something that scared them away well I'd better tell you the whole story yes we'd like to hear the house originally belonged to Richard Holloway seven years ago in 1939 Richard and his wife Diana went on a short queue cruise in their yacht the Viking second that's an interesting name they never came back oh they had two friends visiting them will refuse to go with them the strangest part about it is that these friends warned them that they'd never return live from the cruise all the way he's left it oh well well how did they know these friends at the Holloway's wouldn't come back I don't know nobody knows well did you talk to these friends no I never saw them I only know about it through John Gabriel he was the Holloway's butler been dead for two years now as a matter of fact even Gabriel didn't know these friends he'd never seen them before it's a mystery that I've thought about for years I'm afraid it's gonna be a mystery forever very interesting but we'd still like to buy the house Mr. Smith there was a light shining in one of the windows when we were there yesterday we also heard a clock shining that's funny no one's been inside that house in over a year oh Eva perhaps we ought to think this over nonsense darling you're not gonna let some old wives tail bother you are you no no but how could a clock still be going if no one's been in that house for a year well there's a life boy not far from the house you might have mistaken it for the clock now you see everything has a logical explanation yeah what about the light in the window well it was probably a reflection from the sun or something we'd like to take the house Mr. Smith well if you wanted I'd be glad to sell it to you I just thought it fair to tell you all about it so if anything happens you can't blame me here we are darling our house I hope we'll like it of course we will let's go in do you have the key dear yes but we don't need it the door was open remember yes that's right it's locked again oh mr. Smith must have locked it everything clean dusted why it's spotless oh now mr.  Smith why he thought of everything bedroom is even bigger than I thought look at the beds right someone slept in that man mr. Smith sent to clean the house must have slept in it yes and he apparently slept in both bed this library look at that paneling yeah it's a very lovely room everything is charming but but what look at the fireplace what's wrong with the fireplaces that is just some half burnt logs in it yes just some half burnt logs still smoldering well it was the cleaning man I don't think there was a cleaning man now don't be absurd Fred the clock we heard the first time we were here Eva I just can't shake off the feeling that someone is still living here you're being ridiculous maybe I am but I feel like an intruder darling it's that story mr.   Smith this is Fred Jordan oh everything seems fine thanks for having the house cleaned up didn't you send a cleaning man to straighten up the house might interest you to know we found the house in a spotless condition cleaned and ready for occupancy thank you mr. Smith I'll be in touch with you later we'd better go back to the house please don't be upset there must be some logical explanation maybe maybe somebody took advantage of a boarded up house and was living in it rent free I'd like to correct your dear someone is still living in it besides ourselves sometimes Fred you get very ridiculous maybe let's go back inside look what is a fire burning in the fireplace now what's wrong with that I haven't touched this fireplace since we got here you didn't look table is set for tea did you do this no I didn't tea pot is hot somebody somebody must be hiding if they are I'll find them come on I just sell her to attic and there's no one here someone is living here and we can't see it doesn't make sense there's somebody here right now right in this room it sounds crazy but I know it Fred the clock what about it it it just struck midnight and it's it's only 10 o'clock a house that is deserted except for invisible tenants and a clock that is running backwards has it just struck 12 for murder at midnight and now back to murder at midnight and the house that time for God red week up get up what what is it dear what's matter look out there out the window why get up and take a look at what boat out there in the inlet it must have put in while we were sleeping can't you read the name dear it's the Viking second the Viking set wasn't that the Holloway's yet the one that never came back that's what mr. Smith said either mr. Smith is a fantastic liar or something very fantastic is happening to us perhaps the Holloway's have finally come back after seven years doesn't make sense none of it that's putting it mildly telling we we ought to take a close look at the boat don't sound very enthusiastic about it yes I suppose we ought to whoever is on it might be able to tell us something somebody must have come off the boat they couldn't have dear at least they didn't come up to the house well let's let's go up and see all right going on deck there anyone here no answer maybe they're down below they must be I'd rather not go down there we've got to find out let's let's both go down together all right you keep right behind me don't worry dear I will here's the state room there's nobody here either anybody here no one at least but the beds are still warm but I just left the state room a little while ago it seems so let's get out of here Eva gotta cure your feeling down my spot it is chilly lights are on in the living room did you put them on just one of the lamps a floor well all the ceiling lights are lit the doors locked we didn't even close it when we went out no I remember we left it open good evening who are you I beg your pardon I said who are you I'm John Gabriel butler to the Holloway's Gabriel that's right man whom do you wish to see we don't want to see anyone we live here I'm afraid you're mistaken sir the Holloway's live here I've been living here for years but this is our house we bought it and the Holloway's are dead dead yes I'm afraid someone has misinformed you listen this is like a nightmare look here Gabriel or whoever you really are we bought this house from Cecil Smith a real estate agent in Westfield he's not the kind of a man who plays practical jokes no he's not he's a very sober man indeed he told us you were dead too as you can see madam I'm very much alive this is crazy we'd better talk to the people who call themselves the Holloway's perhaps you should there'll be in any minute please come in won't you you excuse me if I close the windows we're going to have a storm perfectly all right would you care for some tea look here Gabriel we've been waiting an hour for mr. Holloway and his wife they haven't shown up and I don't think they will not just what is your game would you care for some tea mrs. Jordan no thank you did you hear what I said yes sir I did as soon as mr. and mrs. Holloway arrived I'm sure you'll be convinced of your error they should be here any minutes since they plan to leave tonight on a cruise this is mad fantastic ah they've come just missed the storm Gabriel oh hello I don't believe I know you this is mr. and mrs. Jordan mr. and mrs. Holloway I'm glad to meet you mrs. Jordan mr. Jordan thank you are you Richard Holloway yes I can't believe it it's all terribly confusing mr. Holloway these people claim that this is their house what that they bought it from Cecil Smith they also claim that you mrs.  Jordan oh before I forget Gabriel get our suitcases aboard the yard will you we'll be leaving in a few minutes yes sir right away do you suppose that maybe we're dreaming this we are we're dreaming it together I'm sorry I don't know how this happened to you perhaps you better stay here for the night there's plenty of room and we'd be delighted to have you would you mind if I call mr. Smith oh please do the phones right there on the table I know thanks operator operator let me have Westfield 403 hello mr. Smith this is mr. Jordan Fred Jordan remember you sold me the Holloway house yes you must be mistaken I never sold it that property is not for sale are you talking about listen mr. Smith you know very well who I am you won't get away with this I'll have you brought into court now I never heard of you in my life you must be crazy goodbye hello hello he hung up what did he say he said he never sold the house he'd never even heard of me he must have been taken in by someone who posed as mr. Smith that's really a shame you have to be very careful we'd be glad to have you stay here till you find other quarters well I as a matter of fact you can stay for a few days until we get back we're taking a trip on our boat perhaps you'll be able to get it all straightened out in the morning I just don't understand it the mr. Smith we had dealings with wasn't a crook I know he wasn't that was my feeling too but I you're not going out to see in this kind of weather we don't mind a little rain my husband's a very good sailor Mrs. Jordan he can handle the Viking second in any kind weather sounds like a gale coming up we like them exciting well it's dangerous to set out in this weather they're very dangerous oh now don't worry about us we don't drown easily darling we better get started oh yes yes I'm also are the suitcases aboard yes Gabriel took something's wrong with your grandfather clock it only struck eight times yes it's correct my watch says eight o'clock too well how can that be it's after midnight you really are mixed up mr. Jordan it's only eight o'clock well my watch says 130 well so does mine I'm afraid ours is right Mrs. Jordan it's very old but very accurate of course there's a legend about it the story is that it will sometimes go backwards in time has has that ever happened no no it's only a story it's never gone anything but forward like any other clock but it's a nice story isn't it yes yes delightful might even be true Mrs. Halloway yes what is today's date what I believe it's September 10th what what year 1939 of course 1939 yes yes of course that Mrs. Halloway I'd I'd like to ask you and mr. Halloway something yes please please don't go out on this trip you're planning why not because if you do I don't think you'll ever come back what a terrible thing to say please Mrs. Halloway please I don't know what's wrong with you too you came in here with a strange story about owning my house and now you tell us we're never going to come back she's right you won't come back you'll pardon me for saying so mr. Jordan but I think you're both crazy I don't care what you think but please don't go why Mrs. Jordan I have a hunch about it we don't believe in hunches it's more than a hunch mr. Halloway I know you're not coming back if you'll excuse us I think we'd better get started come along darling I'm ready I put everything on board is there anything else yes just take care of our guests see that they're comfortable goodbye Gabriel goodbye and pleasant voyage make yourself at home and we'll be back despite your hunches if you wish you could occupy the master bedroom I'll go up and make it ready for was there anything else you wished mr. Jordan ma'am no Gabriel just go to bed we'll we'll sit here for a while it's rather late sir nearly midnight by your clock Gabriel but it's it seems to have stopped so it has it needs rewinding it's going now yes seems to be ticking rather first something's wrong it never did that before something's happening as soon as I find the switch I don't know maybe the storm lightning where's Gabriel Gabriel never mind you can't catch a fight the switch here it is oh all all that dust like the first time we saw the house there there is no Gabriel we're back in 1946 and that means he's dead you mean the clock did go backwards something else you understand too now don't you we were the friends that mr. Smith told us about the mysterious friends that urged the Holloway's not to go on that trip what clock is stopped it needs rewind no no don't touch it we we won't wind that clock again ever a house without tenants except for the dead and the clock that runs backward in time if it was your clock would you wind it or are you afraid it would keep you up nights while you waited for it to strike 12 for murder never to be with us again when death comes out of the past out of time gone by and the clocks strike 12 for murder the Jordan's husband and wife were played by Vinton Hayworth and Elsie Hitts with music by Bert Berman murder at midnight was directed by Anton M. Leader


Okay all right guys what is going on? It's Jacob here welcome back to the channel welcome to my latest reaction video today's video is gonna be on Usain Bolt who is one of my all-time heroes he is definitely one of my all-time heroes I would absolutely love nothing more than for him to still be running you know what I mean still be out there just like an NFL player would coming to the end of their career you know they might have lost it a little bit of a half-step in their speed in their strides you know what I'm saying but they'd still be out there but unfortunately in top-level sprinting and and if and you know setting not only world records but triple gold medalist in the hundred meter 200 meter and a hundred meter relay except for one you know that's that's that's not something you can maintain for too long but Usain Bolt did it for over eight years 12 years he was at the 04 Olympics then went to 08 then 12 then 16 he is an absolute legend but unfortunately not running anymore anyways there's a video that came out not too long ago title what they never told you about Usain Bolt and I think it might have something to do with the 400 meter dash being that he never really ran it he certainly didn't run it at the Olympic Games so we're gonna watch that first it came out about two weeks ago what came out about four days ago is another video on Matthew bowling and look I'm gonna be honest Matthew bowling look I'd um I'd love to shake your hand because your video your my reaction video to you was one of the most popular videos and well-received videos on my channel in the year of 2020 so for that I say thank you and for for your career the entertainment the spectacle that we're gonna see we're gonna experience watching your career throughout your life I'm grateful for that too and it hasn't even happened yet but the guy who paved the way was Usain Bolt now the video that came out four days ago Matthew bowling was apparently him setting some sort of 400 meter record and so when I saw that I was like well I've seen something on Usain Bolt possibly about 400 meter so if Matthew bowling is effectively the next Usain Bolt but he's already competing in also the 400 meter as well as the hundred and 200 he might be even greater than Usain Bolt you know what I'm saying do you see what I'm saying so that's fucking exciting but what's even more exciting is this video here because Matthew bowling hasn't done anything yet Usain Bolt is a living legend and we're about to see what they never told you about Usain Bolt so let's go this should be good he's considered by many to be the greatest track and field athlete of all time look at him go with nine Olympic golds 11 world championship golds and a stunning amount of breathtaking victories Usain Bolt has submitted his name as the greatest male sprinter of all time absolutely no doubt in the world 2016 he was simply on another level of speed race after race year after year and I enjoyed every single one human however there is something else that many do not realize about this Jamaican legend and that's that at the young age of 16 he was considered by many not to be the future of the 100 or the 200 but the future of the 400 meters you're kidding you're kidding he began in the 400 bolt entered the Jamaican high school national championships in the 400 meters at the time he was actually the defending world junior champion over the 200 meters however on this day doesn't even look like Usain Bolt look at him run doesn't even look like him he worked on his technique didn't he 200 meters however on this day in the one lap race his time was so fast that it improved on the previous national high school record look at him go look at those strides I mean he's the same height as them but his stride is so long it's like he's just got different tendons right it's almost like he's built like a kangaroo you know I'm saying there's just there's just more spring in his step than most other men and he doesn't have an ounce of fat on him so I mean that helps 45.35 seconds remember that given that this time was done in the rain and that he eased up over the final it was quite clear that his 400 meter potential was much higher and then just one month later he would run one of the most stunning 4x400 meter relay legs in high school history it's not over for this particular race I want you to pay attention to just how far behind Usain Bolt is from the front runner oh shit I didn't even see him however over the next lap he showcased one of the greatest sprinting achievements in high school history down the back stretch he powered away effortlessly from the center and coming through the final 100 meters well there was simply nobody that was gonna catch him now I've watched this race many many times this performance on numerous occasions I've clocked this 16 year old bolt at 44.8 seconds a pretty remarkable time for such a young athlete the potential of Usain Bolt and the 400 meters was nearly limitless but as we all know his future would be in the 100 and the 200 meters oh guys I've got ghost bumps man looking at this shit those those angles those camera angles man he was already six foot in the 100 meter sprint absolutely towering over his peers with Usain Bolt leading the charge it looked like he was a sprinting superhero there ain't nothing like it this larger stature certainly made him and especially when he got so far ahead that he relaxed for the last 10 meters I mean you didn't know what he was gonna do he might turn to the crowd he might turn backwards he might do a cartwheel no I never did that we might have actually oh my god yeah 400 was out the door let's do the 200 instead under 20 seconds and it was certainly a strong foreshadowing moment of his 200 the question still remains how fast could bolt have yeah how fast could he have been that that is the question that is the question what is the world record in order to see success in the four fleets needs tremendous strength in addition to natural speed now both certainly has natural speed there's literally no one that would disagree with that but he rarely brought out his 400 meter strength in competition the 400 meter is just brutal instead of building up additional muscle throughout his career both maintained a leaner and lighter stature nothing like the hundred meters he had done this track history would likely be quite different but it's also hard to imagine that bolt would not have been an absolute killer in the 400 meters he already made running under 45 seconds at just 16 look quite easy so just imagine what he could have accomplished at 18 years old or even 20 or even 22 for that matter one clear example that showcases his undeniable 400 meter potential comes from the 2010 Diamond League meeting in Ostrava 300 okay interesting let's have a look at this he still ran the second fastest performance in the history of the 300 meters at the time this performance completely destroyed oh my god he could have got under 40 seconds for the 400 meters he what is the world record 400 this time is unbelievable he could keep going for another hundred meters no doubt notice the track is actually wet and that's because there was actually light rain during his race this undoubtedly slowed down his overall time but what I found just adds to his legacy was how he finished the final 100 meters even though he was much heavier than the rest of the field the final 100 meters was where he completely buried his competition yeah yes he did oh it's amazing but still this final stretch was a real showcasing of his 400 meter bro look at the technique it's different it's different when he was younger right he keeps his head right over the top of his body rather than like that quite amazing that bolt was in fact Wade Vanneke see that's the 400 meter runner isn't it Vanneke so 43.18 you are joking you are joking so that means bolt has to run the final 100 meters of his 400 meter dash in what in what 13 seconds 30.97 so under so 12 12 12 point in fact let's let's work this out 4th 43.18 43.18 meters 12.21 12.21 seconds Usain Bolt would have to have ran in this exact race the last 100 meter dash in which he do in his sleep he do it backwards for God's sake he would be the world record holder in the 400 meter dash if he ran it ever and it recorded me I'm telling you this right now damn because the only athletes to ever run faster than this okay well look he ran well he ran probably as pretty much as well as he could and he still didn't beat Michael Johnson in the 300 meter now that last 100 meters from 3 to 400 would be the toughest in the fucking world especially especially if you've just run 300 meters in 30 seconds flat but I reckon he could have done it I reckon he could have done it I reckon he could have shattered the world record just like he did in the 200 and just like he did in the 100 I'm gonna say right here right now that if you say about trained for it if you say about trained for the 400 he could have got at least under 43 if not under 42 seconds and that would have been something to behold for many bolt had obvious world record potential in the 400 meters and many have speculated that he could in fact have run well under 43 seconds this kind of performance would easily still be a world record but unfortunately we'll never know just how no we won't that is really unfortunate what times could you say involved have run in the 400 meters had he focused on this event leave your thoughts in the comment section down below thanks for watching everyone and as always until next time I'm actually glad he put that question out there because I'm gonna say I look I would have obviously would have done pretty fucking well to get under 42 seconds I'm gonna say 42 5 and that would have been just absolutely smashing the world record of 43.18 I'm gonna say he would have come in at a meet made it you know coasted in right maybe an Olympic games coasted in through his heat like he always does coast in through the semi get to the final and then put the fucking hammer down and he would have ran a 425 a 4 2.5 that's what I'm saying but what are these guys say in his absolute God world record prime in 2009 he should have signed up for competitive diamond league 400 meters to break 43 I think you could have done it so do why okay people have put their answer underneath the question for 3.21 or 4 2.89 well that makes absolutely no sense Matthew could have broken 43 42.958 under 43 42.5 42.7 42.81 43.13 4275 there's someone that said I think he would have struggled to break 44 to be honest unpopular opinion I know he struggled with too many 200 meters as it is though did he really did he really well at the end of the day when it counted in the Olympic games he came through and that is why he is the legend he is today so thank you for watching thank you for listening in the next one we're gonna watch Matthew bowling shocking the world and I cannot wait so I will see you all then thank you so much for watching like I said I am extremely sunburnt today she's not good mate she's not good she's not a good look gotta watch the Sun around here man you gotta watch the Sun I'm hoping this clears up I don't want to red face forever but that's what you get when you go out in the Sun in New Zealand in summer there's no ozone layer here anyways guys I do want to say a quick thank you to all of the new subscribers anyone that is watching this video and haven't you know for the first time hasn't seen me before I want to say thank you so much and at the end of the day all these videos are just for fun I create the content that I enjoy you know what I mean if I wasn't enjoying what I was watching then I wouldn't be making this video and you can count on me for at least that if nothing else at least that so with all that being said thank you so much for watching have a great day and I will see you in the next one peace out


Thousands of people on the outskirt of Thailand's capital have been evacuated and five fighters battled blazes for hours after a factory explosion that killed one rescue worker and wounded 29 people. Authorities say rest in Samut Prakhand Province, who live within a five kilometer radius of the factory, owned by a Taiwanese company where being moved away as a precaution. Now local disaster authorities said 70 houses were damaged and fires were still being fought nine hours after the explosion in the early hours of Monday. The cause of the blast had yet to be determined.


We're talking today a lot around the AirPods Pro, but in the wider context we're looking at them as an example of a change that's happening in the hearing technology landscape. And we're seeing a drive to improve access and affordability of hearing technologies with a lot of new products recently coming on the market. Now I'm particularly interested in apps and devices to help people hear and communicate better. When the new hearing features were introduced for the Apple AirPods Pro, I was really keen to explore them. So here I'm going to share some of the most interesting insights and learnings. So first up, what are the hearing features available in Apple AirPods Pro? How to set them up and personalize them as hearing devices? Were they going to look at the performance characteristics and go through some capabilities and limitations? So what are the hearing features available in AirPods Pro? Now most people who own AirPods Pro probably bought them as a nicely designed earphone with good quality audio, integrates well with their phone. They probably don't realize that they also contain some really useful hearing features. So here are some that I think are quite useful. Firstly, there's live listen. Now this has been around a while since 2014 and that's when you can use your iPhone as a remote microphone and you place it closer to the person speaking and it streams the amplified audio direct to your AirPods or your compatible hearing aids. And it's really useful in a noisy environment or if you're listening from across the room. Now the AirPods Pro also have three noise control modes. There's active noise cancellation. So apart from the obvious benefit where you can cancel out annoying sounds, you can also listen to let's for example your music or podcast in noisy environment without having to turn the volume level up really loud so you can maintain safer listening levels. The other really interesting one here is transparency mode and that's when you can let the outside sound in and be more aware of what's happening around you. The next one, background sounds. This has recently come in. You can listen and play calming sounds like a stream or the sound of rain and this can help alleviate tinnitus. And then the last two, what we're really interested in for this talk, headphone accommodations. You can customize your headphones to your hearing needs and individual preferences so you can hear sound clearer and also conversation boost. And this is to help hearing better and noise. So to delve into those last two a bit further, headphone accommodations. It was released in iOS 14 so like 2020 what it does is it amplifies the sounds based on the user's hearing needs. And there's a few different ways where you can set this up. You can use an audiogram which is going to give you the most personalized sound or you can do quick A, B listening comparisons. You can hear different versions of speech or music and choose the one you prefer and the system will choose the appropriate preset profile. So they have three preset profiles called balanced tone, vocal range or brightness and they can be applied at three different strengths. Now a really good benefit of the headphone accommodations is that there's no Bluetooth delay in the processed audio and if you've used some hearing amplification apps you may have noticed a delay or echo that affects the listening experience. With the AirPods Pro they do the audio processing in the H1 chip in the AirPods in the ear so you don't get that delay from relaying the audio from the phone to the earphone. And headphone accommodations can be applied to phone calls, media and to the sounds around you. That last one of course making AirPods more like hearables. Now the next one conversation boost this was released with iOS 15 so just towards the end of last year it aims to help improve communication and noisy environments. So we know that hearing impaired people have increased difficulty understanding speech and background noise. We can think of this as sort of like a directional mode. So in the Apple terms it uses computational audio and beamforming to focus on the person speaking in French. At the same time it's attenuation sounds around the listen to the background noise. So it's these two features headphone accommodations and conversation boost that we're most interested in when we're comparing the AirPods to hearing aids. So now we're familiar with the main hearing features how do we set them up and personalize AirPods Pro as hearing devices. Now it's not as easy as one might expect. It's actually these features are buried in layers of menus and set up can be a bit tricky. So this next part of the talk is a kind of tutorial but rather than rehash some of the instruction guide that are out there I'm going to focus specifically on how to tune headphone accommodations using an audio ground and also share some helpful tips.   You want to switch headphone accommodations on and then go to custom audio setup. Now this recording will be available after the event so if you don't capture everything now you can check back later. So then we want to add a custom audio gram. So we go to add audio gram and there's a few different ways we can do this we can use the camera to take a photograph of the audio gram you can use a photo that you've already got stored or you can upload a file for example at PDF. I'm going to go through and take a photo with the camera because that's kind of fun. In this example I just pulled up an audio gram on my screen on my monitor but you could equally have one printed out on paper and the iPhone goes directly to camera mode you don't have to do anything it actually automatically finds that audio gram in the camera view and takes a photo so you don't even actually have to press that button down the bottom and it then displays what it thinks is the audio gram. Now I think that that looks pretty good I'm quite happy with that you can try and retake that photo if you want but we can move on and then it analyzes the audio gram and this part does require an internet connection. If you don't have internet available you can enter the values manually but with an audio an internet connection it'll go through and pull out the relevant hearing thresholds from that image. Now we see that it does pretty well but it's not perfect and we can scroll down if we want and look at some values that are missing and go in and enter those manually and correct any others that it may have not quite got right. Generally I find that if there are hearing thresholds that are the same in the left and the right ear it tends to miss one of them but you can go through and then confirm your data. Now one thing I've noticed is that the it's limited to the frequencies you see here so 125 hertz up to eight kilohertz in octave steps and there doesn't seem to be a way to and push any other frequencies that you might have. The next step is then to listen to audio samples with the recommended settings so that's using this audio gram that you've just put in and you can go through and listen to it switch between the custom the customized audio or the standard and choose the one you like. So if it's all working well the one that uses the audio gram should sound better to you. So that's the setting up with the head fund accommodations to the audio gram. What I also recommend is to do an ear tip fit and what this will do is just check that the ear tips you've got the right size they're sealing in the ear canal properly and that can really affect the sound quality it can affect the performance of the noise reduction and then just make things generally more comfortable.  So this is the test you want to place the AirPods in your ear which they should be already if they're connected and when you press play it will play some music. Now you want it and it will come back with a result for each ear. Now in this case it's come back with a sort of a yellow result where it says adjust or try a different ear tip so you just want to try wiggling it around see if you can get a better fit and if that doesn't run the test again if that doesn't work you may want to switch to one of the different ear tip sizes. But with a good result it comes back green that's a good seal and the right size will not only be more comfortable it would reduce audio leaking out she'll get better low frequencies and reduce that ambient noise leaking in. The second tip I have is to create a hearing short catch in the control center. To do this go to settings and then control center. You want to look at that the hearing icon is not in the included controls so scroll down and find it and then press the little plus icon next to hearing. Now what that will do is when you go to control center it will put down the bottom this extra button with the ear on it so that's your hearing shortcut control and what that means is that you can then now do adjustments for headphone accommodations from the control center and you don't have to go back into all those accessibility setting menus. So when you press on that you can see all the AirPods options headphone accommodations you want to make sure transparency is in there so that they're going to work as hearing devices you can adjust the amplification so that's like a volume control the balance which is the balance between the left and the right audio channels scroll down a bit further you also have control over the tone so whether it's more low frequency darker or more high frequency which they call brighter and you can adjust the ambient noise reduction and turn conversation boost on or off. So these parameters can be easily adjusted by the user in the situation in the current situation however they feel they need extra boost or not. All right so how are we going out we're all set up what is the performance characteristics of AirPods Pro hearing features. So we performed electric acoustic and measurements in the lab both in quiet and in background noise. First we wanted to determine the amount of amplification and the frequency response provided by headphone accommodations and for these measurements we used an ear simulator which is widely used for standardized acoustic testing of headphones and hearing aids and we did measurements with the speech stimulus level at three levels so 50 dB SPL which is a soft speech level 65 an average level and an 80 dB SPL a loud level and these are the profiles the headphone accommodation gain for two preset profiles at moderate strength so for the balanced tone profile on the left we see that headphone accommodations gain at a level of 65 dB SPL gave a boost of about 12 dB between two and five kilohertz and we can see the compression there's more amplification for soft sounds than there is for the loud sounds on the right for the brightness preset there's more boost in the high frequencies with a 15 dB gain at four kilohertz at that 65 dB SPL input level. Now looking at how much gain control the user has with the quick adjustment settings with the amplification control they can slide it from zero to one hundred percent and this gives them a 12 dB range of gain adjustment cool and with the tone control this is a spectral tilt which pivots around about 1.5 kilohertz and going from zero percent which is the darker setting to a hundred percent brighter the user can increase amplification of the high frequencies by eight dB while simultaneously decreasing the low frequencies by up to four dB. Now if we want to look at how much gain can get a better fitting of sorry if we want to get a better understanding of what the fitting algorithm is in the AirPods Pro we can look at in pushing a custom audiogram and measuring the output levels so here are two custom audiograms we've looked at we've got one with a mild to moderate sloping loss from 20 to 50 dB HL and a flat 40 dB loss and we want to know how headphone accommodation gains compares to a typical hearing aid prescription so we can see here again the headphone accommodations gain but the solid lines at 50 65 and 80 dB SPL speech levels and we compare that to the null and our two prescriptions of the insertion gain which is shown by the dotted lines and we can see a really close match in the red which is the average speech levels but there's greater amplification with headphone accommodation so the yellow at loud speech levels and lower amplification with headphone accommodations at soft speech levels a similar result for the flat 40 dB HL audiogram greater amplification at loud levels and lower amplification at soft levels so we can expect there should be differences for the AirPods Pro compared to hearing aids that have been programmed to match null and our two targets and the audibility of soft sounds and for loudness comfort our next phase was to look at how AirPods Pro perform in background noise so showing here is one of our acoustic test rooms with a circular array of loud speakers we have a person sitting on that chair in the middle wearing AirPods Pro we put Pro Tube microphones in their ear to measure the level near the eardrum there's multi talker babble noise coming out from the speakers at a level of 65 dB SPL and we use a signal to noise ratio of minus 3 dB which is quite a challenging or common signal to noise ratio experienced for example in restaurants and then we use this phase inversion method to calculate the signal to noise ratio I won't go into too much detail but basically we play two successive recordings one with the phase of the speech signal converted and then when we subtract those signals we can extract the speech when we add them we can extract the noise and then calculate the signal to noise ratio so looking at the effect of these new features so there's conversation boost and ambient noise reduction we calculated the difference in the signal to noise ratio between using headphone accommodations with these features compared to what with these features turned on that is compared to when they're turned off and then to relate that SNR advantage to speech intelligibility we applied band important weights that were based on the speech intelligibility index so with this arrangement with noise coming from five speakers located to the side and the rear there was about a four and a half to five and a half dB advantage due to conversation boost being forming and this correlates to the directionality in hearing aids which increases speech intelligibility there was also around about a two dB advantage due to ambient noise reduction and noise reduction generally improves listening comfort so we saw there were slight differences between hearing loss profiles generally milder hearing losses with less amplification showed less SNR advantage due to conversation boost with a second more challenging arrangement with noise coming from all directions and out of all 16 speakers these measurements were repeated this time we've got a near normal audiogram in the hearing profile to match participants that we had in a study that was running in parallel with AirPods Pro and compared to the unaided condition we see the SII weighted SNR advantage overall of 5.3 dB but 3.2 when we're looking at just the conversation boost feature and this can be compared to hearing aids with conventional directional microphones that provide a three to six dB SNR improvement in diffuse noise right so just a quickly referencing to a study that was run by Rakeem Valdorama Venezuela where we were evaluating the benefits of AirPods Pro with normal hearing participants that had self-reported hearing and noise difficulties and just on one of the results from that study the speech and noise testing that was done with the same arrangement that we just showed that arrangement too with the noise diffuse around the listener the AirPods Pro provided a 12 percent increase in speech intelligibility compared to the unaided condition and on subjective ratings they said that with the AirPods Pro it was less mentally demanding it improved performance and required less effort so just the last section what are the capabilities and limitations of AirPods Pro I've mentioned quite a few of these already so for capabilities improved audibility of sound improved SNR and reduced background noise other things to consider the lower cost than hearing aids reduced stigma some people don't like the look of traditional hearing aids they have that active noise cancellation mode and another good thing is that there's frequent firmware updates so they're constantly getting new features without you needing to do anything extra on the limitation side we've seen that there's a limited control over the fitting parameters you don't have that flexibility to adjust the fitting like you do with a hearing aid fitting software the gain of the soft and the loud levels differs from some hearing aid prescriptions I didn't mention previously you can't set up the left and right is separately so the same profile actually gets used for both ears so that may be an issue if someone has an asymmetrical hearing loss they also lack some advanced features of hearing aids and they're more for situational use not for all day wear because of the battery life and some comfort issues so to close off as an overall summary the AirPods Pro now include features that give them hearing aid like functionality setting up the AirPods requires a number of steps and know how to get the most out of these devices and tune them to individual needs and I hope that the steps earlier can help with that our acoustic measures show that AirPods Pro provide frequency and level-dependent amplification and improve the SNR in noisy environments and while they do have limitations they may be a good low-cost situational use option for people with hearing difficulties that are not ready for hearing aids so that brings us to a close and thanks for listening I'd also like to thank my colleagues who have contributed to this work so Paul Heyman here,
