The ear is a complicated piece of anatomy. Simply put, sound waves pass through the ear canal causing the eardrum to vibrate which in turn moves the small bones of the middle ear. The movement of the last small bone taps on the cochlea — the spiralled tube known as the inner ear — which is filled with liquid and microscopic cells including stereocilia that have hair-like endings.
