7.1 Audition

Question 1

Loudness

Answer 1

Perseption of the intensity of a sound

Question 2

Amplitude

Answer 2

The intensity of a sound wave

Question 3

Pitch

Answer 3

The related aspect of perception

Question 4

Frequency

Answer 4

The number of cycles per second, measured in Hz

Question 5

Tympanic membrane

Answer 5

The eardrum

Question 6

Pinna

Answer 6

The outer ear structure of the flesh and cartilage that sticks out from each side of the head

Question 9

Oval window

Answer 9

A membrane of the inner ear

Question 10

Place theory

Answer 10

Consept that pitch perception depends on which part of the inner ear has cells with the greatest activity level

Question 11

Volley principle

Answer 11

Tenet that the auditory nerve as a whole produces volleys of impulses for sounds even though no individual axon approaches that frequency

Question 14

Primary auditory cortex (area A1)

Answer 14

Area in the superior temporal cortex in the which cells respond best to tones of a particular frequency

Question 16

Hair cells

Answer 16

The auditory receptors that lie along the basilar membrane in the cochlea

Question 17

Tinnitus

Answer 17

Frequent or constant ringing in the ears

Question 18

Cochlea (KOCK-lee-uh, Latin for “snail”)

Answer 18

Structure in the inner ear containing auditory receptors

Question 20

Frequency theory

Answer 20

Consept that the basilar membrane vibrates in synchrony with a sound, causing auditory nerve axons to produce action potentials at the same frequency

Question 22

Nerve deafness (inner-ear deafness)

Answer 22

Hearing loss that results from damage to the cochlea, the hair cells, or the auditory nerve

Question 26

Conductive deafness (middle-ear deafness)

Answer 26

Hearing loss that occurs if the bones of the middle ear fail to transmit sound waves properly to the cochlea
