Speechreading in actual use depends on both auditory and visual input for
most clients. The measure of speechreading ability that best reflects a client's
real ability is one that is administered in a combined auditory-visual mode.
One component of the adult aural rehabilitation process is listening training. In
listening training, the patient is trained to - ✔✔be alert, attentive, and set
to receive communication
Being alert, attentive, and set to receive communication are the
important components to improve listening skills.
,During subjective verification of hearing-aid directionality, a patient indicates that
when noise comes from behind, the noise seems especially loud. Which of the
following is most likely the cause? - ✔✔The microphones are probably
wired backward.
Directional microphones are designed to reduce sounds from behind the listener.
If the listener perceives that sounds are loud from behind, likely the front
microphone is functioning like the back microphone and undesirable sounds are
not being cancelled from behind.
Hearing-conservation programs for children often include screening with pure
tones and acoustic immittance measures, whereas such programs for adults
will likely use only pure tones for screening. Which of the following justifies this
difference? - ✔✔There is a significantly higher incidence of middle-ear
pathology among children than among adults.
,Acoustic-immittance measures, although they do not test hearing sensitivity,
detect the possible presence of middle-ear pathology. For appropriate hearing
care, therefore, both acoustic-immittance and pure-tone measures are necessary
for children.
Which of the following is true of the occlusion effect observed during pure tone
audiometry? - ✔✔It can affect the measurement of bone-conduction
thresholds at low frequencies.
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.
, Diagnostic audiometers generally provide one-third-octave noise bands for use in
masking pure tones. This bandwidth is used because bands of that width -
✔✔Encompass the width of a critical band
Narrow bands of masking noise should be wider than a critical band so that they
will provide good masking for the frequency being tested without requiring high
overall intensity just to achieve effective masking levels on that one frequency.
It is important to consider the gestational age of an infant, rather than the
chronological age, when interpreting which of the following? - ✔✔ABR Wave
V latencies
An audiometer attenuator is set to 0 dB HL. Which of the following is true about
the sound pressure level output at the earphone? - ✔✔It is lowest
at midfrequencies.
