✔✔graph shows steadily rising masking effect. At 75dB HL there is a plateau all the way
to 90dB. After that is rises again
According to the contralateral masked-threshold function shown in the figure above,
which of the following values represents the true threshold for the test ear?
A.50 dB HL
B.55 dB HL
C.65 dB HL
D.75 dB HL
E.95 dB HL - ✔✔Correct Answer: D
Option (D) is correct. According to the plateau method of determining true threshold, the
true threshold is reached when the threshold of a test ear remains stable over a range
of at least 20 dB increase in masking intensity. In the figure, the test-ear threshold
plateaus at 75 dB.
✔✔Which of the following reflects the compression ratio for the input-output function at
50 dB SPL?
A.2:1; 50 dB SPL
B.1:1; 50 dB SPL
C.4:1; 90 dB SPL
D.3:1; 50 dB SPL
E.5:1; 90 dB SPL - ✔✔Option (A) is correct. The compression ratio is the change in
input over the change in output. From 50 to 60 dB SPL, there is a 10 dB change in
input, with only a 5 dB change in output, resulting in a 2:1 compression input.
✔✔A research study tested the hypothesis that individuals with symmetrical hearing
loss who have been fit with one hearing aid would demonstrate improved speech
recognition in background noise with increases in head angle. Fourteen individuals were
,fit monaurally with a behind-the-ear (BTE) hearing aid with directional and
omnidirectional microphone modes. Speech recognition performance in noise was
tested using the audiovisual version of the Connected Speech Test (CST v.3). The test
was administered in auditory-only conditions as well as with the addition of visual cues
for each of three head angles: 0º, 20º, and 40º.
Results indicated improvement in speech recognition performance with changes in head
angle for the auditory-only presentation mode at the 20º and 40º head angles when
compared to 0º. Improvement in speech recognition performance for the auditory +
visual mode was noted for the 20º head angle when compar - ✔✔Correct Answer: D
Option (D) is correct. This is an experimental study because one variable (head angle)
is manipulated under highly controlled conditions to see if changes in head angle
causes any changes in another variable (speech recognition).

Option (B) is correct. Speech recognition performance is a dependent variable because
it is affected by head angle, which is manipulated in this study under highly controlled
conditions.

, Option (B) is correct. This is a within-subjects design because the variable of head
angle is being manipulated to determine if speech recognition improves within each
subject, with each subject serving as his or her own control.
✔✔A patient who has a sudden profound sensorineural hearing loss with poor word
recognition in the left ear undergoes a complete otological evaluation, including a
prescribed course of steroids, an MRI, and serial audiograms. The otologist determines
that the loss is irrreversible and refers the patient to an audiologist for follow-up. The
most logical next step for the audiologist is to
A.fit the patient with a power behind-the-ear hearing aid on a trial basis
B.suggest the patient enroll in speechreading classes
C.try a transcranial CROS hearing-aid with the patient
D.make a referral to another otologist for a second opinion
E.make a referral to a speech-language pathologist for information regarding speech
conservation - ✔✔Correct Answer: C
Option (C) is correct. A transcranial CROS hearing aid reroutes signals from the poor
ear to the better ear via bone conduction.
✔✔Under Occupational Safety and Health Administration (OSHA) regulations adopted
in March 1983, a standard threshold shift on an annual audiogram is defined as a
change in hearing threshold relative to the baseline audiogram of an average of 10 dB
or more at which of the following frequencies?
A.500, 1000, and 2000 Hz
B.1000, 2000, and 3000 Hz
C.2000, 3000, and 4000 Hz
D.500, 1000, 2000, and 3000 Hz
E.500, 1000, 2000, and 4000 Hz - ✔✔Correct Answer: C
Option (C) is correct. OSHA's definition of standard threshold shift involves 2000, 3000,
and 4000 Hz only.
✔✔An adult with a progressive sensorineural hearing loss is no longer able to use a
standard telephone at work. The managing audiologist should assist the patient with
A.learning a manual communication system
B.obtaining a job that does not require spoken communication
C.obtaining reasonable accommodation for telephone communication at work
D.working with vocational rehabilitation to be considered for a cochlear implant
E.using an assistive listening device that alerts the client that the phone is ringing -
✔✔Correct Answer: C
Option (C) is correct. The audiologist should counsel the patient about reasonable
accommodations in the workplace mandated by the Americans with Disabilities Act.
