hearing notes

Question 1

frequency (pitch)

Answer 1

dimension of frequency determined by wavelength of sound measured by hertz

Question 2

intensity (loudness)

Answer 2

amount of energy in a wave determined by amplitude; related to perceived loudness, measured in decibels

Question 3

cochlea

Answer 3

coiled, fluid-filled tube in the inner ear that transducers sound vibrations

Question 4

frequency theory

Answer 4

the rate of impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch

Question 5

place theory

Answer 5

sound frequency stimulate basilar membrane at separate places resulting in perceived pitch

Question 6

localization of sound

Answer 6

because we have 2 ears, sounds that reach one faster than the other makes us localize the sound

Question 7

noise-induced hearing loss

Answer 7

the pressure inability to detect higher frequency sounds do
damage the hair cells accused over time

Question 8

conduction deafness

Answer 8

hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerve, nerve deafness

Question 9

sensorineural deafness

Answer 9

hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerve

Question 10

cochlear implant

Answer 10

a small, complex electronic device that can help to provide a sense of sound to a person who is profoundly deaf or severely hard of hearing
