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


1.  A potential advantage of deep fitting hearing instruments include
  1. reduction of the occlusion effect
  2. more gain required to achieve the same SPL as traditional hearing instrument
  3. natural protection from wind noise
  4. All of the above
  5. A and C
2.  Technology put into hearing instruments today that allow the creation of the IIC product includes
  1. better feedback control
  2. better noise management
  3. remote control options
  4. All of the above
  5. None of the above
3.  Shell manufacturing that has allowed the creation of this custom model includes
  1. the ability to scan impressions
  2. the ability to optimize component location
  3. ability to minimize the number of contact points for comfort
  4. All of the above
  5. B and C
4.  The "Pinna Effect" refers to
  1. the ability to wear glasses
  2. the high frequency emphasis the pinna provides to our hearing
  3. the ability some have to pin their ears back
  4. the low frequency pick up offered by the concha bowl
5.  Placing the microphone of the IIC at the second bends provides a directivity index
  1. that is less than the open ear
  2. that is better than the open ear
  3. that is about the same as the open ear
  4. DI doesn't really matter, so we don't have to worry about it
6.  Boyle's law
  1. is for bowling
  2. says that less energy is needed to produce desired SPL at the TM than with a traditional hearing instrument
  3. says that more energy is needed to produce desired SPL at the TM than with a traditional hearing instrument
  4. deep microphone placement will allow better localization
7.  Custom deep fitting products have the advantage over stock products by
  1. taking individual anatomy into consideration
  2. allow greater customization of fitting, both through programming and physical design
  3. allow a customized, more comfortable fit
  4. All of the above
  5. None of the above
8.  Some criteria for patients who can wear the IIC include
  1. their ear canal must have the physical size to support the product
  2. their ability to sing and dance
  3. their hearing loss (thresholds and MCL) must be appropriate for the gain available
  4. All of the above
  5. A and C
9.  An impression for an IIC must have
  1. 8 mm beyond the 2nd bend
  2. 8 mm height at the 2nd bend
  3. 4 mm width at the 2nd bend
  4. All of the above
  5. A and C
10.  The HearLens features
  1. Axio ST 32 techology
  2. T2 and T2 On Demand
