How many decibels is thunder? Answers. Best Answer: Up to about 120 decibels, which is about as loud as a gunshot. Some of the factors that affect the loudness are energy released, the environment, and of course the distance you are from the lightning.

The Sound of Thunder Regardless of whether lightning is positive or negative, thunder is produced the same way. Thunder is the acoustic shock wave resulting from the extreme heat generated by a lightning flash. Lightning can be as hot as 54,000°F (30,000°C), a temperature that is five times hotter than surface of the sun!

Pascal (unit) In measurements of sound pressure or loudness of sound, one pascal is equal to 94 decibels SPL. The quietest sound a human can hear, known as the threshold of hearing, is 0 dB SPL, or 20 µPa. The airtightness of buildings is measured at 50 Pa.

- You are surrounded by sounds of varying decibels every day, most are well below the danger level, such as office conversation or white noise from a humming air conditioner (both are about 60 dB). But, noises that are 85 dB or higher put your hearing at risk.

How much damage is caused by hearing gun fire? Temporary hearing loss can result in sustained noise levels of 85 decibels, or intermittent spikes of sound of 110 to 120 decibels; sustained sound at this level, or spikes at heavier levels, can cause permanent hearing damage,

The Why Files Thunder — the cracking or rumbling you often hear — is caused by thermal expansion and contraction. Lightning bolts can get far hotter than the sun’s surface — up to 20,000° Celsius. That heats the air, causing it to expand, and starting a shock wave that moves as sound waves — thunder.

Does Lightning Make Noise? Thunder, the sound that follows lightning, comes from rapid air expansion around the lightning bolt. The heat from lightning causes the air around the bolt to reach temperatures of over 40,000 degrees Fahrenheit rapidly. The heated air compresses then explodes outwards, forming a shock wave and creating a loud noise.

- NHRA dragsters reach 155-160 decibels. A space shuttle launch is 165-170. The call of a blue whale (largest and LOUDEST mammal on Earth) can reach 188 decibels. In 1883 Krakatoa, the volcano, erupted and the sound was reported at 180 decibels. The sound was heard almost 3,000 miles away. A 1-ton bomb reaches 210 decibels.

Portable Generator Noise Levels: Understanding Decibels (dBA) Generally speaking, noise levels are measured in decibels (dBA), a metric commonly listed on generator specification sheets. Noise levels can vary significantly based on generator size and the manufacturer, ranging anywhere between mid-50 and mid-80 dBA. So, how do you know exactly how loud is too loud?

Beans and Legumes: Are they Paleo? “Dry beans and peas are the mature forms of legumes such as kidney beans, pinto beans, black-eyed peas, and lentils. These foods are excellent sources of plant protein, and also provide other nutrients such as iron and zinc. They are similar to meats, poultry, and fish in their contribution of these nutrients.eans are not good sources of either zinc or iron, and they have low protein digestibility because these legumes are chock full of antinutrients that impair our body’s ability to absorb and assimilate potential nutrients found in these foods.

- The lightning and thunder sound occur at the same time, but an observer will experience a delay in hearing the thunder depending on the distance from the lightning strike.  …  Light travels at slightly less than 3.00 x 106 kilometres/second or around 1.88 x 106 miles/second. That is fast.

- With doubling the distance from a sound source the decibels decrease by 6 dB. So a jet engine sound can be at 12.5 m distance 130 dB. At 25 m distance 124 dB, at 50 m distance 118 dB and at 100 m distance only 114 dB. You see how important it is to tell always the distance with the measured decibel level. Don't believe that only a specific decibel value belongs to noise source.

What Causes Thunder? Thunder is caused by the sudden expansion of the air around a lightning bolt's path. The deep rumbling and sharp cracks of thunder are produced as the air around the lightning bolt is superheated — up to about 54,000° Fahrenheit (about 33,000° Celsius) — and rapidly expands.

Thunderstorms & Lightning: The Underrated Killers! The air near a lightning strike is heated to 50,000 degrees. Fahrenheit, which is hotter than the surface of the sun. Rapid. heating and cooling of air near the lightning channel causes a. shock wave that results in thunder. Thunder from a nearby. lightning strike will have a very sharp crack or loud bang.

- For example, usual conversation is approximately 60 decibels, the humming of a refrigerator is 40 decibels and city traffic noise can be 80 decibels. Examples of sources of loud noises that cause NIHL are motorcycles, firecrackers and small arms fire, all emitting sounds from 120 decibels to 140 decibels.

76 (dB) Decibels (or dBs) are how sounds are measured usually on a range from 0 dBs to 120 dBs. A whisper would be about 30 dBs. 75 -80 dBs would be the sound that an air conditioner or vacuum cleaner would make. A subway train would be about 100 dBs.

The Sound of Thunder In addition, the temperature of the atmosphere affects the thunder sound you hear as well as how far away you can hear it. Sound waves move faster in warm air than they do in cool air. Typically, the air temperature decreases with height.

- The closer you are, the shorter the gap between the lightning and thunder. The speed of sound is around 767 miles per hour (1,230 kilometres per hour). The speed of light is around 669600000 miles per hour (1080000000 kilometres per hour). Thunder is difficult to hear at distances over 12 miles (20 kilometres).

- Since sound travels about 1 km every 3 seconds (or 1 mile every 5 seconds), and the extend of lightning is of the order of several km, thunder usually lasts several seconds. You hear different parts of the lightning channel(s) as the thunder continues. Thunder of IC lightning.

- After you see a bolt of  lightning, for every 3 seconds until you hear the thunder, it means  it is one kilometer away (3 seconds = 1 kilom…eter). This is because  the sound wave created by the lightning is traveling at about 330  m/sec (in dry air, the speed of sound is about 343 m/sec or 1127  ft/sec).

Can you calculate how far away lightning struck by thunder? It is possible to figure out how far away a lightning strike is with some simple math­. Officially, the speed of sound is 331.3 meters per second (1,087 feet per second) in dry air at 0 degrees Celsius (32 degrees Fahrenheit). At a temperature like 28 degrees C (82 degrees F), the speed is 346 meters per second.

- Confidence votes 4.9K. No, 10 dB is perceived to be twice as loud, and requires 10 times the power. Doubling of the volume (loudness) should be perceived by a level difference of 10 dB − psychoacousticians say.Doubling the sound pressure (voltage) level corresponds to a measured level change of 6 dB.Doubling of acoustic power (sound intensity) level corresponds to a calculated level change of 3 dB.4 decibels is about as loud as sitting 8 to 10 feet away from stereo speakers. 74 decibels is almost the same as the sound of a washing machine it is just 1 decibel higher.

Truth Test | Can you count the seconds between lightning and thunder to determine distance? It takes roughly five seconds for the sound of super heated air or thunder to travel one mile, so if you see a flash of lightning and count 10 seconds until you hear the thunder, you need to divide by five to determine this storm is roughly two miles away.

Between what decibel levels does instantaneous damage to hearing loss occurs? What is the decibel level of a drum line? On average, about 120 db, depending on size. What are the decibel levels for the hearing impairment classifications? It is important to understand that a decibel is just a unit of measure that is used to determine loudness of a sound or amount of hearing loss.
