  1. Noise reduction works both long-term and also extremely rapidly
  2. Speech signals from the back and sides are treated the same
  3. The directional system isolates it's knowledge from the noise reduction process
  4. All of the above
2.  Open Sound Navigator in OPN2 and OPN3:
  1. Works exactly the same way as OPN1
  2. Uses the same principles as OPN1, but with less effect
  3. Only operates using directionality
  4. None of the above
3.  The Noise Removal in Open Sound Navigator:
  1. Can create a new noise reduction solution for each phoneme
  2. Looks only at the broadband characteristics of noise
  3. Works only on soft noises
  4. None of the above
4.  In Open Sound Navigator, the analysis:
  1. Is updated only when the overall level of the talker changes
  2. Is updated approximately 100 times per second
  3. Works only on the broadband signal
  4. None of the above
5.  The Analysis stage:
  1. Is something that was also used on our previous Inium Sense platform
  2. Is typical of all modern hearing aids
  3. Required the processing power of the Velox platform
  4. All of the above
6.  The Analysis Stage feeds information about the nature of the sound environment to:

  1. Only adjust the Noise Removal portion
  2. Only adjust the Balance behavior of the product
  3. Adjust both the Balance and Noise Removal
  4. None of the above
10.  In the Open Sound Navigator:
  1. A backward facing polar plot provides an estimate of the noise to be eliminated
  2. The directionality works rapidly in sixteen channels
  3. Noise reduction is assisted by knowing the characteristics of the noise signal from the back and sides
  4. All of the above
