ABRs can be used to estimate________ at different frequencies
What is auditory thresholds
100
In order to determine a client's threshold, you must have two responses in the ______ direction
What is ascending
100
measure of contraction of the stapedius and tensor tympani muscles
What is acoustic reflex
100
SRT should be in agreement with the _______ within _____dB HL.
PTA
10
100
T/F 2-4 of every 1000 births have a hearing loss
What is TRUE
200
Occupational exposure to high-intensity noises accounts for ____percent of all adults with moderate hearing loss
What is 10%
200
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
200
Measures the sound reflected from the ear drum while the pressure of the external canal is varied by the operator. It aids in the assessment of outer ear, middle ear and the Eustachian tube. This test should not be performed in infants below the age of 7 months because the suppleness of the cartilage of the external canal may produce misleading results.
What is Tympanometry
200
Characteristics of a conductive hearing loss
Usually temporary
Can usually be treated medically or surgically
Simply reduces the volume of signal
Maximum loss of 60 dB
200
What are risk factors for otitis media?
Cigarette smoke
Allergies
Feeding position
Breastfeeding
300
What is the most common stimulus used to elicit TEOAEs?
What is a click
300
Masked bone conduction thresholds are at 15 dB and air conduction thresholds are at 50 dB, the hearing loss is...
What is a conductive loss
300
Name two things that may cause a Type B tympanogram
What is perforated ear drum or PE tubes, middle ear fluid
If the TM is perforated it will result in a ____type tympanogram
What is B
400
A type B tympanogram with a high ear canal volume may be indicative of...?
Pressure equalizing tubes or perforated ear drum
400
Normal ear canal volume and no peak pressure or compliance
may indicate
What is fluid in the ear
400
Characteristics of a sensorineural hearing loss
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
A type B tympanogram with normal Ear Canal Volume may indicate what?
Fluid

Name and explain the 5 types of tympanograms
What is Type A (normal)
Type AD (abnormal)
Type AS (abnormal)
Type B (abnormal)
High volume
Normal volume
Type C (abnormal)

Explain/describe conditioned play audiometry
What is Testing can usually be conducted under headphones or with inserts for ear specific information. I usually tell them they are going to look like a bug/butterfly or wear a special hat.
Testing is transformed into a game for the child with the use of various methods (throwing a block into a bucket, slapping your hand, touching their nose, etc. Must keep the game very simple and not complicated!!!!
Children that can be conditioned to the task can provide us with a complete audiometric picture in most cases.
