module 20 vocab

Question 1

the number of complete wavelengths that pass a point in a given time

Answer 1

frequency

Question 2

a tones experienced highness or lowness depends on frequency

Answer 2

pitch

Question 3

the chamber between the eardrum and cochlea containing 3 tiny bones (hammer, anvil, stirrup) that concentrate the vibrations of the eardrum on the cochlea’s oval window

Answer 3

middle ear

Question 4

a coiled bony fluid filled tube in the inner ear ; sound waves traveling through the cochlear fluid trigger nerve impulses

Answer 4

cochlea

Question 5

the innermost part of the ear containing the cochlea, semicircular canals, and vestibular sacs

Answer 5

inner ear

Question 6

hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerves; the most common form of hearing loss also called nerve deafness

Answer 6

sensorineural hearing loss

Question 7

a less common form of hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea

Answer 7

conduction hearing loss

Question 8

a device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea

Answer 8

cochlear implant

Question 9

in hearing the theory that links the pitch we hear with the place where the cochlea’s membrane is stimulated

Answer 9

place theory

Question 10

i’m hearing the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, enabling us to sense its pitch (also called temporal theory)

Answer 10

frequency theory

Question 11

the sense or act of hearing

Answer 11

audition
