ABOUT THE EAR

The ear consists of three major compartments, the outer ear, the middle ear and the inner ear. Sound vibrations are collected by the outer ear and travel down the ear canal to the eardrum (also know as the tympanic membrane). When the sound waves reach the eardrum it causes it to vibrate in rhythm with the sound energy it is absorbing.
