INTRO TO AUDIOLOGY EXAM 2 EXPECTED QUESTIONS
WITH VERIFIED ANSWERS
Question 1.
What is the purpose of pure tone audiometry?
ANSWER
To determine the amount of a person's hearing sensitivity at various frequencies
Question 2.
What are the test frequencies on an audiogram?
ANSWER
125 Hz to 8000 Hz
Question 3.
What is the difference between Electroacoustic and Bioacoustic Calibration?
ANSWER
Electroacoustic calibration is done annually. Bioacoustic calibration is done every day the
equipment is used.
Question 4.
How do you perform a listening check?
ANSWER
- Speech audiometry
- Includes a variety of audiometric tests performed with speech stimuli.
- May be performed with recorded stimuli or by "monitored live voice."
Question 5.
What are we listening for during a listening check?
ANSWER
-attenuator linearity
- extraneous scratching/popping sounds as dials or switches are moved
- intermittencies when cords are twisted
,Question 6.
Describe the patient's role and positioning in audiometry.
ANSWER
Patient is given a button to press or is instructed to signal by raising their hand.
For patient's positioning, typically the client should be turned so they cannot see the clinician
while testing.
Question 7.
Describe the clinician's role in audiometry.
ANSWER
The clinician needs to asses each client to determine what type of response strategy is more
appropriate. A good clinician is always on the lookout for false negative/positive responses.
Question 8.
What is a false positive response?
ANSWER
When a patient indicates that they hear a tone when no tone is present
Question 9.
What is a false negative response?
ANSWER
When a patient fails to indicate that they heard the tone (when they actually heard it)
Question 10.
Be able to name the transducer types:
ANSWER
- supra-aural conduction earphones
- insert receivers
- bone conduction vibrator
, Question 11.
What are the benefits
of insert headphones over supra-aural headphones?
ANSWER
- preferred for comfort
- better infection control
- less need for masking
- avoidance of ear canal collapse
increased attenuation of background noise
Question 12.
Describe the procedure for pure-tone audiometry.
ANSWER
- Testing frequencies between 125 and 8000 Hz. - Start at 30 dB HL if no response go up to 50
dB HL then increase in 10 dB each time until a response is obtained - Descend in 10 dB steps
when a response is obtained and ascend in 5 dB when there is no response (up 5 down 10) -
The threshold is the lowest level at which the patient can correctly identify at least two out of
the three tone presentations or 50% of the time
Question 13.
Audiometric Symbols
ANSWER
Right = red
Left = blue
