Studies on the Human Ear

General Definition

The human ear is a sensory organ which collects and analyzes vibrating wave motions in the surrounding medium.

The detection by the ear of a sound wave traveling through the air is determined by the auditory receptors within the ear, as well as the position of the sound source.

Auditory receptors in the ear respond sympathetically to sound waves which vibrate at frequencies ranging from a few cycles per second for low sounds, to thousands of cycles per second for the highest sounds. The amplitude range extends from sounds which are barely audible, to sounds which border on the threshold of pain.

Sound waves which enter the ear are modified in various ways. They are then analyzed, and converted to neurochemical impulses. Finally, the sounds are transmitted to the auditory regions of the brain, producing the sensation of hearing.
