1.  Which of the following is not important to the process of speech perception:
  1. Frequency Cues
  2. Intensity Cues
  3. Binocular Cues
  4. Harmonic Relationships
2.  For SpectralIQ 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
3.  For SpectralIQ to be activated by default, audiometric thresholds below 1000 Hz must be:
  1. 55 dB HL or better
  2. 65 dB HL or better
  3. 75 dB HL or better
  4. 85 dB HL or better
4.  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
5.  The area of the hearing aid frequency response in which high-frequency speech features are recreated is known as the
  1. Target region
  2. Bulls eye
  3. Area of lows
  4. Speech Spot
6.  What 2 characteristics of frequency-lowering are adjustable with Spectral iQ?
  1. Bandwidth and gain
  2. Bandwidth and compression threshold
  3. Gain and expansion
  4. Expansion and bandwidth
7.  Audiometric thresholds between 4000 Hz and 8000Hz that are equal to or greater than 70 dBHL will result in a default bandwidth setting of:
  1. 2
  2. 5
  3. 7
8.  What frequency-lowering technique could be described as a "cut and paste" approach?
  1. Linear frequency transposition
  2. Non-linear frequency transposition
  3. Frequency translation
  4. All of the above
9.  What frequency-lowering technique could be described as a "squeezing" approach?
  1. Linear frequency transposition
  2. Non-linear frequency compression
  3. Frequency translation
  4. All of the above
10.  With Spectral iQ, 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
