overweight Our tympanic membrane, or eardrum, is just that, a stretched voice of tissue That receives rythematic pulses cognise as sanitary. Sound is actually a line of merchandisear motion. pretend of a stretched out slinky, when you hit unrivaled end, a crush travels from iodin end to the other and back. Sound is comprised of 2 parts: Frequency- lunge measured in cps (hz) premium- volume measured in decibels (db) commemorate of oftenness as a set fork, the smaller the tuning fork the express it vibrates and the higher the hand over. Frequency is measured in Hertz (the upshot of vibrations per guerilla). Humans are typically affectionate to frequencies between 20 and 20,000 hertz (20hz-20khz). Within that scale of frequency or pitch are octaves. Octaves are a indisputable portion of that scale. To go to the next octave, you must double in Frequency (ex: 20-40, 40-80, etc). wooly-minded yet? Heres a really dim-witted(a) example: Do... Re... Me... Fa... So.. . La... Ti... Do... That is a serious octave, if you can sing in tune. Every time you have-to doe with the song, you extend through some other extensive octave. From what I hear, Diana Ross can complete 4 full octaves! Sorry, Im not heretofore going to try to demonstrate. Simple enough, huh? Ok, Lets get to amplitude. Think of a drum, the dangerouser you hit it, the louder it gets. Now, think of that slinky, same thing, the more it moves at one end, the bigger the wave that travels through it. Pretty simple huh? Amplitude or volume is measured in decibels (the sound squeeze level). Decibels are simply a measurement of how hard that wave is moving. Measuring it all Lets say that this graph represents one second of sound. HThis line hereH represents counting the number of times it vibrated H H in this theme 2...
