Overview of hearing loss Flashcards
What is conductive hearing loss?
hearing loss caused by damage to the outer or middle ear
What is sensorineural hearing loss?
hearing loss caused by damage to the inner ear or nerve of hearing
What is mixed hearing loss?
a combination of sensorineural and conductive hearing loss
What are the degrees of hearing loss?
hard of hearing (HH) and deaf
What is hard of hearing (HH)?
limited amount of hearing loss
What is deaf?
loss of hearing loss, so much so that you cannot use your hearing in a meaningful way.
What tests are used to determine how much speech has been affected by the hearing loss?
SRT (speech recognition testing), WRS (Word recognition score), and Speech in Noise testing
What do the results of an audiological evaluation indicate?
type of HL, degree of HL, configuration of HL, and the person’s ability to understand speech
What terms would be used to describe the time of onset of hearing loss?
prelingual, perilingual, postlingual, and deafened
What is prelingual hearing loss?
hearing loss that occurred at birth or shortly after
What is perilingual hearing loss?
hearing loss that occurred while the person is developing language
What is postlingual hearing loss?
hearing loss that occurs when the person is 5-10 years old
What is deafened?
HL that occurs when the person is in their late teens or early 20s or when a person completes most of their schooling.
What is the incidence of HL in infants?
2-3 in 1,000
What is the prevalence of HL in adults in the US?
15.7% of adults aged 18 years or old
What are the causes of HL?
otitis media, loud noises, mumps, chicken pox, measles, encephalitis, ototoxic meds, congenital, cold, flu,
What is the difference between describing hearing loss as high frequency vs low frequency?
high frequency HL means that you can only hear high frequency sounds, whereas low frequency HL means that you can only hear low frequency sounds
What is asymmetrical hearing loss?
each ear has a different severity and shape regarding the hearing loss
What is symmetrical hearing loss?
each ear has the same severity and shape regarding the hearing los
What is the difference between bilateral HL and unilateral HL
Bilateral HL is HL in both ears, whereas unilateral HL is in one ear
What is progressive hearing loss?
HL worsens over time
What is sudden hearing loss?
HL that occurs quickly
What is fluctuating HL?
HL that changes over time; sometimes it gets better and sometimes it doesn’t
What is stable hearing loss?
HL that does not change over time
What does configuration of hearing loss mean?
shape of your graph on the audiogram
What range is considered normal hearing on an audiogram?
0 to 20 db
What range is considered mild hearigg loss on an audiogram?
20 to 40 dB
What range is considered moderate hearing loss on an audiogram?
40 to 70 dB
What range is considered severe hearing loss on an audiogram?
70 to 90 dB
What range is considered profound hearing loss on an audiogram?
90 to 120 dB
