Audiology Test 1 ACTUAL Exam Questions
and CORRECT Answers
Why is audiological testing used? - CORRECT ANSWER - to determine the function of
the auditory system
What is the "gold standard" for diagnosing a hearing loss? - CORRECT ANSWER -
Formal audiometric testing (pure tone threshold testing)
NHANES - CORRECT ANSWER - (National Health and Nutrition Examination Survey)
an audiometric assessment of hearing loss is the golf standard objective measure and has been
shown to be reliable in numerous studies
When is audiometric (pure tone) testing useful? - CORRECT ANSWER - when
determining the audibility of environmental and speech sounds in a quiet environment
What is the classical use of audiometric testing? - CORRECT ANSWER - to determine the
presence of "normal hearing" or the degree of a hearing loss
In the past what have the results of audiometric testing been used for? - CORRECT
ANSWER - to determine the need for a hearing aid and "fit" them
Pure Tone Threshold - CORRECT ANSWER - the lowest level at which the patient is able
to detect a pure tone at least 50% of the time
What is the "normal" pure tone threshold? - CORRECT ANSWER - 25 dB
-anything higher represents a hearing loss
Instructions for conventional pure tone audiometry: - CORRECT ANSWER - push the
button/raise your hand whenever you hear the sound no matter how soft
,What is measured in a conventional pure tone audiometry test? - CORRECT ANSWER -
pure tone threshold
-the lowest level at which the patient can hear the sound at least 50% of the time
What test sounds are presented during a conventional pure tone audiometry test? - CORRECT
ANSWER - pure tones, warble tones, or narrow band noise
What is the range of frequencies presented in a conventional pure tone audiometry test? -
CORRECT ANSWER - 250-8,000 Hz
What can affect an audiogram? - CORRECT ANSWER - the status of any component of
the auditory system from the ear canal to the cortex
Standing Waves - CORRECT ANSWER - in room like our classroom, if we played a pure
tone, you would be able to move your head and it would effect the sound level
Warbel Tones - CORRECT ANSWER - a tone in which the frequency is modulated with
small rapid changes
-vibrato
Pure Tones - CORRECT ANSWER - simple sound waves that have only one frequency of
vibration
-sine wave
Narrowband Noise - CORRECT ANSWER - band-pass filtered noise concentrated around
a center frequency
-used in clinical pure tone masking
, What is the units of measure for the test result for a conventional pure tone audiometry test? -
CORRECT ANSWER - the test result reveals a threshold so the unit of measure is dB HL
-HL stands for hearing level
What is the name of the x/y plot for pure tone thresholds? - CORRECT ANSWER - an
audiogram
What is the unit of measure for the x value on an audiogram? - CORRECT ANSWER -
frequency (Hz)
What is the unit of measure for the y value on an audiogram? - CORRECT ANSWER -
sound level (dB HL)
How is the x value obtained on an audiogram? - CORRECT ANSWER - the frequency the
tester selects (octave and interactive frequencies)
How is the y value obtained on an audiogram? - CORRECT ANSWER - modified
Hughson-Westlake protocol
How can pure tone thresholds be estimated? - CORRECT ANSWER - with Auditory
Brain Response testing (ABR)
Behavioral Observation Audiometry (BOA) - CORRECT ANSWER - -birth to 6 months
-patient response is the commencement or cessation of sucking
Visual Reinforcement Audiometry (VRA) - CORRECT ANSWER - - 5 to 24 months or
older depending on developmental age
-patient response is a head turn towards a toy in a shadow box
Conditioned Play Audiometry (CPA) - CORRECT ANSWER - -25 to 60 months
