The skin is dried out in the sun and the hair shaved. It is then stretched over the hollowed out, preferably hardwood, drum base. The skin is tightened with leather straps and nailed or pegged on.

Making Music All musical instruments create sound by causing matter to vibrate. The vibrations start sound waves moving through the air. Most musical instruments use resonance to amplify the sound waves and make the sounds louder.

One thing that makes the sabar unique to African drumming is that it’s played by hand AND by stick. The player holds a long, thin stick (galan) in one hand for producing the high notes and also strikes the skin with the empty hand.

According to the Guinness Book of World Records, the loudest (and largest) instrument in the world is the Boardwalk Hall Auditorium Organ.

The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.

Especially dangerous is infrasound at the frequency of 7 Hz, since this sound, generating frequencies, close to characteristic frequencies of the organs of our body, may disturb the heart or brain activity. Machines, natural sources storms, earthquakes, hurricanes, etc. generate infrasound.

A coroner recorded a verdict of natural causes, saying the straight-As student was killed by sudden arrhythmic death syndrome (SADS), a heart disorder which kills 12 young people a week. …

The bones in your ear translate those vibrations into nerve signals, which your brain interprets as sounds. But other body parts can vibrate, too, including your chest. For most of us, this is nothing to worry about. Unless you have a serious heart condition, the pounding bass shouldnt affect your heart muscle.

Also known as the quad-axial, this speaker has a wider range of high frequencies thanks to its extra tweeter and can produce sounds better than speakers with only one. Not only is the bass better than most other speakers’, but the volume is also louder.

It is very natural for a human mind to suspect that, since a 3-way speaker has an extra speaker involved, it’s more probable to sound better than a 2-way system. An optimal crossover setup contributes a lot to the overall sound quality)

2 way speakers are by far the most limited out of the group while 4 way speakers can do the most. With your 2 way speakers, you have just your woofer and tweeter. The 3 way speakers take those two and add a mid-range speaker. Your 4 way speakers are going to take all that and another tweeter.
