An audiologist fit a young woman with binaural digital behind-the-ear hearing aids three
weeks ago. The patient reports that the devices have provided suitable amplification in
most environments, but she complains that low-level ambient noise has been
distracting. In an effort to reduce the adverse noise effect, what adjustment might the
audiologist make to the hearing aids?
A. Increasing the threshold kneepoint
B. Decreasing the threshold kneepoint
C. Enabling wide dynamic range compression
D. Decreasing the gain in all frequency bands
E. Enabling expansion - ANSWER-(E) is correct. Expansion reduces the gain of low-
level ambient sounds.
Diagnostic audiometers generally provide one-third-octave noise bands for use in
masking pure tones. This bandwidth is used because bands of that width:
A. are centered in the frequency range of normal speech
B. encompass the width of a critical band
C. produce more masking than pink noise does
D. produce more masking than half-octave bands do
E. are less than the width of a critical band - ANSWER-(B) is correct. 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.
