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
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
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
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
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
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
, 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
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
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
