Individuals with normal hearing sensitivity in one ear and a
severe hearing loss in the other ear experience which of
the following?
A.An improvement in speech understanding when the
noise is closer to the ear with hearing loss
B.Improved ability to localize when the noise source is
closer to the ear with normal hearing
C.Better speech understanding and localization as the
reverberation time increases
D.More difficulty understanding speech when the speaker
moves closer to the ear with hearing loss
E.Improved localization when the noise is at 0° azimuth
and the source is closer to the ear with hearing loss -
Answer-Correct Answer: A
Option (A) is correct. It is well-known that for individuals
with unilateral hearing loss, speech intelligibility improves
when the more favorably placed ear (i.e., the better ear) is

further from the noise source. When this occurs then the
SNR improves in the better ear.
A patient is seen for a vestibular evaluation with the
primary complaint of persistent imbalance for the past six
months. She states that she had one severe attack of true
rotary vertigo six months ago, and since then fears
another will occur. She has limited her activities, as quick
head movements increase her symptoms. She reportedly
takes meclizine daily.
Videonystagmography results indicate normal saccade,
optokinetic, and smooth pursuit testing. A second-degree
left-beating nystagmus is observed during gaze testing
without fixation. Postactive head-shake nystagmus reveals
a left-beating nystagmus. No positioning or positional
nystagmus is observed. Bilateral bithermal caloric results
indicate a 50 percent right weakness with no significant
directional preponderance.
Based on the above information, the patient most likely
has
A.Ménière's disease

B.a central vestibular pathology
C.a statically uncompensated per - Answer-Correct
Answer: E
Option (E) is correct. Videonystagmography results
normally provide site-of-lesion specific information (i.e.,
caloric irrigations) to determine probable side of
weakness. In this example, the patient had a 50 percent
right peripheral vestibular weakness, suggesting a
peripheral pathology affecting the right side. The
postactive head-shake left-beating nystagmus suggests
that the lesion is dynamically uncompensated.
Which of the following is true of the occlusion effect
observed during pure tone audiometry?
A.It results in artificially poorer thresholds at all
frequencies.
B.It can affect the measurement of air-conduction
thresholds at low frequencies.
C.It can affect the measurement of air-conduction
thresholds at high frequencies.
D.It can affect the measurement of bone-conduction
thresholds at low frequencies.

E.It can affect the measurement of bone-conduction
thresholds at high frequencies. - Answer-Correct Answer:
D
Option (D) is correct.The occlusion effect is the sensation
of increased loudness of low-frequency sounds
transmitted through bone conduction when the outer ear is
blocked. In cases of conductive hearing loss, the greater
the degree of hearing loss, the louder these sounds are
likely to be perceived, so measurement of the bone-
conduction threshold at low frequencies is affected
The caloric test is designed to stimulate which of the
following structures?
A.The utricle
B.The saccule
C.The superior semicircular canal
D.The posterior semicircular canal
E.The lateral semicircular canal - Answer-Correct Answer:
E
Option (E) is correct. The caloric test introduces a
temperature differential that is designed to cause the fluid
in the semicircular canal closest to the stimulus to move.
