Types of Hearing Loss
Usually a temporary loss. Can usually be treated medically or surgically.Simply reduces the volume of signal. Maximum loss of 60 dB.
What is conductive?
This type of loss is...usually permanent. Usually cannot be treated medically or surgically. Reduces volume of signal AND reduces clarity of signal (i.e., reduced frequency resolution). Can range from mild to profound.
What is sensorineural?
Red is to the _____ ear. Blue is to the ______ ear.

What is TRUE
When both air conduction and bone conduction are impaired and there is a gap between air and bone of 5 dB the loss is...
What is sensorineural
This type of audiometry directly tests the cochlea.
What is bone conduction audiometry?
T/F when you are testing bone conduction on the right mastoid process the sound may be heard in both ears
What is TRUE
In order to determine a client's threshold, you must have two responses in the ______ direction
What is ascending
This type of loss is usually caused by a disorder of the inner and middle ear
What is a mixed hearing loss
The difference between SDT and SRT.
What is detect presence of sound and recognize word and repeat involves understanding, comprehension?
The average of the thresholds at 500, 1000, and 2000 Hz.
What is the puretone average (PTA)?
when there is a 20 dB gap between octaves you must...

What is an audiogram depicting a mixed hearing loss will have an air-bone gap, while a sensorineural audiogram will not have an air-bone gap
An ear infection is usually associated with which type of hearing loss?
What is conductive hearing loss
Five transducers that are used with audiometers.
What are a loudspeaker, supraaural headphones, high frequency headphone, insert phones, and bone vibrators?
The frequencies tested during bone conduction
What is 250-4000 Hz?
When administering an air conduction threshold search, when the client responds you decrease the dB by_____and when the client does not respond you increase the dB by______
What is 10 and 5
SRT should be in agreement with the _______ within _____dB HL.
PTA 10
What does is mean if someone has a threshold of -5 dB HL?
You hear 5 dB better than average normal hearing listener.
This graph has frequency (Hz) on the x-axis and hearing level (in dB HL) on the y-axis.
What is an audiogram?
Type of hearing loss produced by damage to the inner ear or auditory nerve.
What is sensorineural?
Describe the loss if....bone conduction thresholds are at 55 dB and air conduction thresholds are at 60
What is moderately-severe sensorineural loss
T/F When the air conduction and bone conduction are impaired and there is a gap of 5 dB between air and bone the loss is mixed
What is FALSE the air-bone gap must be more than 10 dB
