Conductive Hearing Loss
... Sound vibrations are collected by the outer portion of the ear and funneled down the ear canal towards the eardrum. The sounds are then transmitted through three tiny bones in the middle ear called the ossicles. These three bones are named the malleus, incus, and stapes. The stapes carries the sound ...

Sound
In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.
