3.  What technique could be described as a "real-time recreation with feature translation" approach?
  1. Linear Frequency Transposition
  2. Non-linear Frequency Compression
  3. Frequency Lowering
  4. All of the above
4.  Frequency Lowering
  1. Occurs in real-time and only when high-frequency speech features are present
  2. Recreates high-frequency speech features in a lower frequency region
  3. Maintains a broad hearing aid response bandwidth
  4. All of the above
5.  For frequency lowering to be activated by default, the patient audiogram must have a slope greater than or equal to
  1. 10 dB per octave
  2. 15 dB per octave
  3. 20 dB per octave
  4. 25 dB per octave
6.  For frequency lowering to be activated by default, the patient audiogram must have thresholds below 1000 Hz at
  1. 55 dB HL or better
  2. 65 dB HL or better
  3. 75 dB HL or better
  4. 85 dB HL or better
7.  For frequency lowering to be activated by default, the patient audiogram must have thresholds between 4000 to 8000 Hz at
  1. 45 dB HL or worse
  2. 55 dB HL or worse
  3. 65 dB HL or worse
  4. 75 dB HL or worse
8.  The area of the hearing aid frequency response from which high-frequency speech features are identified and translated to a lower frequency region is known as the
  1. Origin Area
  2. Source Region
  3. Speech Banana
  4. Area 51
9.  The area of the hearing aid frequency response in which high-frequency speech features are recreated is known as the
