Document Summary

Audition: the sense or act of hearing. Frequency: the number of complete wavelengths that pass a point in a given time (for example, per second). Pitch: a tone"s experienced highness or lowness; depends on frequency. Middle ear: the chamber between the eardrum and cochlea containing three tiny bones (hammer, anvil, and stirrup) that concentrate the vibrations of the eardrum on the cochlea"s oval window. Cochlea: a coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses. Inner ear: the innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs. Place theory: in hearing, the theory that links the pitch we hear with the place where the cochlea"s membrane is stimulated. Frequency theory: in hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch.
