Sound Notes and The Ear - CE Williams Middle School
... The ear consists of three basic parts - the outer ear, the middle ear, and the inner ear. Each part of the ear serves a specific purpose in the task of detecting and interpreting sound. Outer ear - Sound waves are gathered by the outer ear made up of the ear, the ear canal, and the eardrum. The oute ...

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.
