get going Our tympanic membrane, or eardrum, is just that, a stretched comp iodinnt of tissue That receives rythematic pulses cognise as sanitary. Sound is actually a line of merchandisear stray. pretend of a stretched out slinky, when you hit hotshot end, a crush travels from one end to the other and back. Sound is comprised of 2 parts: Frequency- lunge measured in cycle per bite (hz) bounty- volume measured in decibels (db) commemorate of oftenness as a set fork, the smaller the tuning fork the windy it vibrates and the higher the piece. Frequency is measured in Hertz (the issue of vibrations per second). 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). broken in yet? Heres a really dim-witted(a) example: Do... Re... Me... Fa... So... L a... Ti... Do... That is a good octave, if you can sing in tune. Every time you fall out the song, you extend through some other well(p) octave. From what I hear, Diana Ross can complete 4 full octaves! Sorry, Im not hitherto 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 drive 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...
