1.  Which of the following could affect the effective compression ratio?
  1. Time constants
  2. Vent diameter
  3. Number of channels
  4. All of the above
2.  Which of the following groups of individuals are particularly affected by temporal cues?
  1. Elderly
  2. People with poor working memory
  3. People with severe/profound hearing loss
  4. All of the above
3.  What is (are) the advantage(s) of using fast-acting compression exclusively?
  1. Audibility
  2. Better sound quality
  3. Preserving temporal waveform
  4. Preserving inter-aural level differences
4.  What is (are) the advantages of using slow acting compression?
  1. Minimize noise between pauses of speech
  2. Preserving temporal waveform
  3. Preserving peak-to-peak differences
  4. All of the above
5.  Which group(s) of individuals most rely on audibility cues?
  1. People with good working memory
  2. People with mild hearing loss
  3. People with poor working memory
  4. No listeners use audibility cues
6.  Which of the following is true for a dual compressor?
  1. Use of both slow-acting and fast acting compression at the same time
  2. Primarily uses fast acting and calls upon slow acting when needed
  3. Primarily use slow acting ad calls upon fast acting when needed
  4. Uses slow acting and fast acting compression alternately
7.  The rationale for dual (or variable speed) compressor is (are):
  1. Slow compressor to preserve temporal cues and fast compressor for audible cues
  2. Slow compressor to preserve audible cues and fast compressor for temporal cues
  3. Slow and fast compressor to preserve temporal cues
  4. Slow and fast compressor to preserve audible cues
8.  How would a dual compressor minimize temporal smearing from the use of fast-acting compression?
  1. Use low compression ration
  2. Link nearby channels for compression
  3. Both A and B
  4. None of the above
9.  Which of the following would have the most spectral smearing?
  1. Linear processing
  2. Slowing acting and many channels
  3. Slowing acting and few channels
  4. Fast acting and many channels
10.  What are the advantages of a dual (or variable speed) compressor?
  1. More consistent audibility for soft sounds
  2. More comfort for transient sounds
  3. Good for people with both good and poor working memory
  4. All of the above
