Question 1

what part of the ear does conductive hearing loss effect?

Answer 1

the outer or middle ears

Question 2

why is conductive hearing loss is more prevalent than sensorineural in children?

Answer 2

because of the high rates of otitis media in early childhood

Question 3

what causes sensorineural hearing loss?

Answer 3

outer or inner cell damage in the cochlea

damage to the auditory nerve

Question 4

why is sensorineural hearing loss is more prevalent than conductive in adults?

Answer 4

because it is the cochlea and auditory nerve that are most readily affected by aging, noise exposure, illness, disease, and injury

Question 5

Definition of recruitment

Answer 5

a reduced tolerance for loud sounds caused by cochlear damage

Question 6

Definition of tinnitus

Answer 6

a ringing or buzzing sound in one or both ears

Question 7

Definition of signal-to-noise ratio (SNR)

Answer 7

hearing loss and loss of speech clarity due to inner hair cell damage

Question 8

true or false: people with SNR loss require a greater signal intensity than those with normal hearing

Answer 8

true

Question 9

Cause of neural loss

Answer 9

damage to the auditory nerve

Question 10

hearing loss goes undetected and/or untreated in more than ____% of adults with hearing loss

Answer 10

75%

Question 11

Definition of presbycusis

Answer 11

progressive hearing loss that occurs as a result of aging

Question 12

true or false: presbycusis is more prevalent and severe in women

Answer 12

false - men

Question 13

what is presbycusis characterized by?

Answer 13

hearing loss in the high frequency range of sounds

Question 14

what percentage of the population have a hearing loss?

Answer 14

approximately 10%

Question 15

true or false: incidence of acquired hearing loss increases dramatically with age

Answer 15

true

Question 16

how is hearing loss classified?

Answer 16

etiology, manifestation, and severity

Question 17

true or false: conductive Hearing Loss is more common in children

Answer 17

true

Question 18

symptoms of conductive Hearing Loss

Answer 18

a slight to moderate loss of hearing in one or both ears

Question 19

is conductive Hearing Loss permanent?

Answer 19

no – it is amenable to medical or surgical intervention, so often it is temporary

Question 20

what are 4 causes of conductive Hearing Loss?

Answer 20

otosclerosis

ear wax blockage

otitis media

damage to outer and middle ear structures

Question 21

Definition of otosclerosis

Answer 21

a condition in which abnormal bone growth develops around the ossicles

Question 22

true or false: otosclerosis occurs twice as commonly in women than in men

Answer 22

true

Question 23

true or false: sensorineural hearing loss is more common in children

Answer 23

false - more common in adults

Question 24

true or false: damage to outer hair cells results in difficulty with hearing acuity

Answer 24

true

Question 25

true or false: damage to inner hair cells results in SNR loss

Answer 25

true

Question 26

symptoms of sensorineural hearing loss

Answer 26

a decrease in both acuity and a loss of clarity

Question 27

is sensorineural hearing loss permanent?

Answer 27

typically, yes -- it can be treated effectively with amplification, but hearing cannot usually be restored

Question 28

what are the most common causes of sensorineural hearing loss?

Answer 28

presbycusis and noise exposure

Question 29

four focus areas in assessment of hearing loss

Answer 29

hearing acuity (or degree of loss) type of loss cause of loss speech perception ability in quiet and in noise

Question 30

what is the most effective treatment approach for adult hearing loss?

Answer 30

a comprehensive plan that combines counseling, fitting of amplification devices, and aural habilitation

Question 31

true or false: most third-party payers do not reimburse for hearing aids or adult aural rehabilitation services

Answer 31

true

Question 32

what does aural rehabilitation focus on?

Answer 32

auditory skill building concerns the ability of the person with hearing loss to relearn how to listen
