4.  Which technologies are completive? Extended bandwidth Binaural ILD preservation WDRC All of the above

5.  Automatic voice identification: Is a fictional creation of the television and film industry Makes use of the unique "acoustic-physiology" of each talker Cannot separate talkers of the same gender Cannot separate talkers of the same regional dialect

6.  Which hearing aid technology primarily uses spectral subtraction? Feedback cancellation Classic noise reduction Classic directionality Wide dynamic range compression

8.  Which of the following Gestalt principles are likely involved in spoken language understanding? Closure Continuation Similarity All of the above

9.  The term spoken language understanding: Has no place in an audiological discussion of hearing loss Refers to processes that occur only after the periphery has identified phonemic elements More closely represents the task of the listener compared to the term "speech understanding" Is out of date and should no longer be used
