Specialist Polar Patterns: Hypercardioid and Subcardioid A hypercardioid mic is like a supercardioid on steroids; the front pickup angle is even narrower and focused, which results in greater rejection of unwanted noise and feedback. To give you an idea, the typical pickup angle on a supercardioid mic is around 115 degrees, whereas a hypercardioid can be as low as 105 degrees.

What's the current theory of how the moon was formed? Current theory is that a large 'wandering' planet, roughly the size of the moon impacted with the earth destroying the earth then a new earth and the moon formed. Another planetary body, Orpheus, collided with Earth at an angle and sent debris into space. The debris collected together to form the current Moon.

- Brief Description of Test: An echocardiogram (often called echo) is a non-invasive test that uses sound waves (ultrasound) to. provide pictures of the heart's valves and chambers and to evaluate the pumping action of the heart. In certain situations, your physician will order an echocardiogram with a bubble study. is added to the basic echocardiographic study. cardiologist will be able to tell if there is a hole or defect in the septum of the heart. (IV) will be inserted into one of your arm veins before the exam begins.

Overview Carotid (kuh-ROT-id) ultrasound is a safe, painless procedure that uses sound waves to examine the blood flow through the carotid arteries. Your two carotid arteries are located on each side of your neck. They deliver blood from your heart to your brain. Carotid ultrasound tests for blocked or narrowed carotid arteries, which can increase the risk of stroke. The results can help your doctor determine a treatment to lower your stroke risk.

Microphones In the magneto-dynamic, commonly called dynamic, microphone, sound waves cause movement of a thin metallic diaphragm and an attached coil of wire. A magnet produces a magnetic field which surrounds the coil, and motion of the coil within this field causes current to flow.

- Idiopathic Hypertrophic Subaortic Stenosis. Subaortic stenosis is a harsh, diamond-shaped, mid-systolic murmur heard best at the left sternal border. Maneuvers that change the murmur include the fact that it becomes louder during a PVC, softer on the beat following PVC, softer with squatting, and louder with standing.diopathic Hypertrophic Subaortic Stenosis.

Microphone Buying Guide Frequency Response. A microphone’s frequency response refers to the range of frequencies, from low to high, that a microphone will pick up. This range is referred to by its lowest and highest frequencies, measured in hertz. A microphone with a frequency response range of around 80 Hz to 15 kHz would make a good choice for a vocal mic. However for miking snares and toms, you would look for a range that starts lower, at around 50 Hz, and for a bass drum mic, you will want a low end of 40 Hz or even lower, down to 30 Hz.

Condenser VS Dynamic Microphones â Differences Condenser mics are one of the most popular in recording studios. They are mainly used on instruments with lots of dynamics and less volume – sudden transients. Vocals (no metal brutals), acoustic guitars, violins and everything less transient oriented are mostly suited for condenser microphones.

Microphone Since a conventional speaker is constructed much like a dynamic microphone (with a diaphragm, coil and magnet), speakers can actually work in reverse as microphones. The result, though, is a microphone with poor quality, limited frequency response (particularly at the high end), and poor sensitivity.

Cardiac Event Recorder Quick facts: 1  A cardiac event recorder makes a record of your electrocardiogram (ECG or EKG) when you have fast or slow heartbeats, or feel dizzy or like you want to faint. 2  Some cardiac event recorders store your ECG in memory in the monitor. 3  There are no risks when using a cardiac event recorder.

- Defined. The echocardiogram is a non-invasive, painless procedure which uses a transducer to transmit high-frequency sound waves (ultrasound) within the heart chambers and valves. These waves bounce throughout the heart area and produce the images that detect heart damage and/or disease.n echocardiogram--or echo--is a diagnostic test used to take pictures of the heart and surrounding blood vessels.

Multi-Pattern Microphones: What, Where and How? While the cardioid polar pattern is undoubtedly the most often used in live sound applications (after all, the ubiquitous Shure SM57 and SM58® microphones are both cardioid types), there’s a case to be made for models that, with the flip of a switch (or the changing of a head) offer directionality options.
