View Course Details Please note: exam questions are subject to change.


1.  How do the acoustics of music differ from speech?
  1. Music has higher crest factors than speech
  2. Listening levels are higher for music than for speech
  3. In the short term, music is wideband while speech is narrowband
  4. All of the above
2.  Which hearing aid processing features might be problematic for music perception?
  1. Feedback suppression
  2. Frequency lowering
  3. Noise reduction
  4. All of the above
3.  Previous studies on music perception in hearing aids indicate that people prefer which of the following?
  1. Fast-acting compression and an extended low-frequency response
  2. Fast-acting compression and a restricted low-frequency response
  3. Slow-acting compression and an extended low-frequency response
  4. Slow-acting compression and a restricted low-frequency response
4.  What is the common characteristic among the music programs of the hearing aids used in the current study?
  1. Feedback suppression was disabled
  2. Noise reduction was disabled
  3. Gain was decreased
  4. Directionality was disabled
5.  The study findings suggest that the conditions rated highest in music quality had what in common?
  1. Better representation of intense low-frequency inputs
  2. Extended high-frequency response
  3. Flatter frequency response
  4. Overall wider dynamic range
