Audiology Praxis Test UPDATED Exam
Questions and CORRECT Answers
For which of the following instruments do national standards or uniform performance standards
for calibration exist?
a. Pure tone audiometers
b. OAEs
c. ABR
d. all have calibration standards - CORRECT ANSWER - Pure tone audiometers
Only pure tone audiometers have established (ANSI) standards for calibration
Which is most likely to be introduced deliberately by an examiner during an audiometric exam?
a. distorted tone
b. switching transients
c. masking noise
d. none of the above - CORRECT ANSWER - Masking noise
distorted tones are an error
switching transients are sounds from turning a stimulus on/off (shouldn't exist)
Sound requires a hearing mechanism to receive it. The other three necessary components include
the following except:
a. vibration
b. medium
c. force
d. velocity - CORRECT ANSWER - Velocity
Velocity isn't required for sound transmission
It is a characteristic rather of medium, or the particles through which sound are traveling
The outer ear is classified as what kind of device?
,a. Mechanical
b. Acoustic
c. Hydraulic
d. Biological - CORRECT ANSWER - Acoustic
The outer ear collects and funnels acoustic energy
It doesn't perform mechanical movement
It doesn't contain fluid like the inner ear
It doesn't analyze sound energy and transmit it as an electrical impulse
The middle ear is classified as what kind of device?
a. Acoustic
b. Mechanical
c. Both of these
d. Neither of these - CORRECT ANSWER - Both of these
Tympanic membrane collects acoustic energy; the acoustic energy is transferred into mechanical
energy through the ossicular chain
The inner ear is classified as what kind of device?
a. Mechanical
b. Hydraulic
c. Biological
e. All of the above - CORRECT ANSWER - All of the above
The hair cells mechanically transmit energy
The endolymph (fluid) moves from incoming sound causing the movement of the hair cells
It analyzes sound based on frequency and intensity and transmits that sound to the brain
Without the middle ear, if sound reached the inner ear it would be
a. virtually nonexistent
, b. so loud it would cause nerve damage
c. distorted in frequency
d. impossible to interpret - CORRECT ANSWER - Virtually nonexistent
without the middle ear approx. 99.9% of sound would be reflected back to the atmosphere
because the impedance of the inner ear is so much greater than that of the atmosphere
The middle ear amplifies sound by approximately 17 times
Which of the following is most likely to cause conductive hearing loss?
a. presbycusis
b. otitis media
c. noise exposure
d. birth trauma - CORRECT ANSWER - Otitis media
middle ear infection causes swelling and fluid buildup in the middle ear space preventing sound
to reach the inner ear
chronic infections cause cause damage to the ossicular chain as well
Which is most likely to cause sensorineural hearing loss?
a. a foreign object
b. impacted cerumen
c. Meniere's disese
d. serous otitis media - CORRECT ANSWER - Meniere's disease
Fluctuating fluid buildup in the cochlea causes damages to the hair cells typically resulting in a
low frequency HL
Which is not a true statement of conductive and sensorineural hearing losses?
a. Conductive hearing losses are often reversible
b. sensorineural hearing losses are usually permanent
c. sensorineural hearing losses impair discrimination
