AP Psychology Module 20 Flashcards

5337850631	Audition	the sense or act of hearing	0
5337850632	Frequency	the number of complete wavelengths that pass a point in a given time (for example, per second)	1
5337850633	Pitch	a tone's experienced highness or lowness; depends on frequency	2
5337850634	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	3
5337850635	Cochlea	a coiled, bony, fluid-filled tube in the inner ear; sound waves traveling through the cochlear fluid trigger nerve impulses	4
5337850636	Inner Ear	the innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs	5
5337850637	Sensorineural Hearing Loss	hearing loss caused by damage to the cochlea's receptor cells or to the auditory nerves. (Also called nerve deafness.)	6
5337850638	Conduction Hearing Loss	hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea.	7
5337850639	Cochlear Implant	a device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea	8
5337850640	Place Theory	in hearing, the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated	9
5337850641	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	10
5337858441	Volley principle	Alternating frequencies combine to form pitch	11
