  1. Feedback management system
  2. Fitting software platform
  3. Technology platform
  4. All of the above
2.  Leakage of sound from a hearing aid when a patient is still is considered the _______________ pathway?
  1. Static
  2. Real time
  3. Dynamic
  4. Acoustic
3.  Leakage of sound from a hearing aid when a patient is moving or touching the aid is considered the _______________ pathway?
  1. Static
  2. Real time
  3. Dynamic
  4. Acoustic
4.  Which of the following statements about spectro-temporal modulation (STM) processing is TRUE?
  1. It is an added signal that attenuates the feedback path
  2. It can prevent feedback from occurring
  3. It replaces traditional acoustic feedback with a soft, non-intrusive sound
  4. All of the above
5.  Which of the following is TRUE about phase cancellation?
  1. It is considered the industry standard
  2. It is capable of suppressing feedback without degrading speech
  3. It generates a signal that is 180 degrees out of phase to cancel the feedback signal
  4. All of the Above
6.  Which of the following is a benefit of AFC Pro feedback management system?
  1. 6 dB added stable gain
  2. Improved target match
  3. More open fit options
  4. All of the above
7.  AFC Pro uses inverse phase cancellation to control static acoustic feedback and ________________ to control dynamic acoustic feedback?
  1. Spatial awareness
  2. Spectrogram cancellation
  3. Spectro-Temporal Modulation
  4. All of the above
8.  Which of following is TRUE about AFC Pro and the EXPRESSfit Pro fitting software?
  1. The AFC Pro feedback manager does not need to be measured unless you have audible feedback
  2. The AFC Pro feedback manager should be measured at every first fit
  3. The AFC Pro feedback manager is automatically measured when you first detect the hearing instruments
  4. None of these are true
9.  Which of the following is an accurate definition of acoustic feedback?
  1. Sound that is amplified gets re-amplified and causes a high pitch squeal
  2. Sound that is leaked to the receiver because of earmold venting
  3. Sound that is very loud and low-pitched
  4. All of the above
10.  Which of the following best describes how STM processing is used in the AFC Pro feedback management system?
  1. An extremely slow adaptation to the static feedback pathway is achieved
  2. A modulated signal is briefly applied to break the feedback loop and help suppress feedback
  3. A modulated signal is used to replicate feedback with a more intrusive signal
  4. Acoustic feedback is modulated and applied to an inverse phase cancellation system
