Sound Essays -- essays research papers
Resonance and Sound physical science and MusicSince toilsome is the medium of music, most of the physics of music is the physics of sound.Its important to remember that sound waves ar compression waves. You can practise a compression wave by stretching out a slinky (you do have a slinky, dont you?) and flicking your finger against a coil at the end. Sound waves are not like the waves on the ocean or the waves you get by waving a stretched-out rope.Take a tune fork (you do have a correct fork, dont you?) and whack it on your knee. What do you hear? Unless you hold the tuning fork right following(a) to your ear, you wont hear much of anything. This is because a small tuning fork cant boost very much bank line around. Now take the same tuning fork, whack it on your knee again, and touch the non-forked end to a tabletop or other handy wooden surface. The sound should be a plenty louder. This is because the vibrating tuning fork causes the tabletop to vibrate. The tabletop can pu sh much more air around than the fork alone. If you touched the end of the tuning fork to a hollow box or, say, the body of a guitar, the sound would be as yet louder. This is because the vibrations get transferred to the air inside the box, which vibrates as well. If the dimensions of the inside of the box are a multiple of the wavelength of the sound, some of the sound waves will reinforce for each one other for even more volume. If a vibration or sound wave can excite another butt into vibrating, the second object is sai...
