Document Summary
Causing vibration, that sends off sound waves that hit your ear which causes us to hear the actual noise. A repetition of rising and falling pressure: the pattern of up and down, is what hits your ear and causes you to hear the noise. Changes in the pressure of air, as a result of some sort of audition. Need a medium for a change of pressures to go through: water. If you"re (cid:272)lose to so(cid:373)ething, there is a bigger change in pressure meaning it will sound louder. Ou(cid:374)d does(cid:374)"t tra(cid:448)el as far (cid:448)ersus i(cid:374) air: air. Frequency: how often it repeats itself in some interval of time, measure the frequency in per second/hertz, sound travels at a constant rate of speed in any medium. You could be measuring the distance between peeks: shorter wave lengths, shorter frequency/ longer wave lengths, longer frequency. Amplitude: how far up and down you go on the pressure axis.
