diseases of audiology

Question 1

aprox what percent of people over the age of 18 have hearing loss

Answer 1

15%

Question 2

does hearing loss increase with age

Answer 2

yes

Question 3

about 10% of adults have experienced ____

Answer 3

tinnitus

Question 4

true/false: only about 16% of adults with hearing loss use hearing aids

Answer 4

true

Question 5

audiologists treat impairment of auditory and ___ function

Answer 5

vestibular

Question 6

vestibular assesments consist of testing for ability to:

Answer 6

maintain an upright posture, coordinate complex movements, and maintain a visual target while moving

Question 7

common vestibular-related issue:

Answer 7

vertigo (spinning feeling)

Question 8

Vestibulo-ocular reflex (VOR):

Answer 8

connects the vestibular neural
pathway in the brainstem to neurons that reflexively control the muscles of the eyes to maintain a clear visual image during head
movement.

Question 9

Vestibulospinal reflex (VSR):

Answer 9

connects from the vestibular nuclei in
the brainstem to motor neurons that control the relevant skeletal muscles; this helps control the body when unexpected changes in
position occur relative to gravity.

Question 10

what does VNG balance test do

Answer 10

test for rapid eye movement

Question 11

Posturography assesses an individual’s:

Answer 11

functional balance, change in body weight distribution

Question 12

VEMP measures:

Answer 12

the electrical activity in one’s neck muscles

Question 13

otoscopy looks at

Answer 13

ear wax, possible diseases in outer/middle ear

Question 14

whats impedance

Answer 14

opposition to the sound energy (healthy ears will have less impedance)

Question 15

whats admittance

Answer 15

how much energy flows through the middle ear

Question 16

impedance and admittance are all categorized under the word _____ and part of the ____ hearing system

Answer 16

immitance, conductive

Question 17

how is immitance used in a tympanometry

Answer 17

ear canal is pressured, which pushes the tympanic membrane into middle ear, reducing its ability to vibrate in response to the tone.

Question 18

what range of db is considered “normal” hearing

Answer 18

-10 - 20

Question 19

what % would someone have to get on their WRS to have excellent/normal hearing ability

Answer 19

90-100%

Question 20

?/6 children develop an ear infection before they’re 3yold

Answer 20

5/6

Question 21

the acoustic reflex threshold measures

Answer 21

the contraction of the stapedius
muscle in response to loud sounds.

Question 22

otoacoustic emissions are commonly used for: and test the:

Answer 22

newborn hearing screenings, cochlea function

Question 23

the auditory brainstem response test presents a series of ___ ___ that measure neural response

Answer 23

broadband clicks

Question 24

true/false: Listeners of tone
languages and speakers of non-tonal languages have the same FFR accuracy

Answer 24

false.

Question 25

for pure tone optometry, the goal is to identify the lowest intensity for a particular tone that can be heard ___ of time the time

Answer 25

50%

Question 26

pure tone optometry is usually done through air conduction (headphones) but can also be done through

Answer 26

bone conduction

Question 27

what are spondee words

Answer 27

two syllable words with roughly equal stress on each syllable (usually compound)

Question 28

energetic masking:

Answer 28

when the frequencies of the noise overlap with the freqencies of the signal

Question 29

informational masking:

Answer 29

when your attention is shifted to recognizing/understanding speech when you’re supposed to be focused on another stimuli
