1.  What was NOT a predicted advantage of digital hearing aids? programmability multiple memories feedback cancellation self-learning capability

2.  When was the first digital hearing aid developed? 2007 1982 1925 1966

3.  Early digital hearing aids did not take full advantage of new logic capabilities were modeled after existing analog devices both A and B None of the above

4.  Multiple memories have great potential benefit were confusing to the patient when first introduced in digital hearing aids are effective and easy to use, for the most part All of the above

5.  Digital hearing aids differ from Analog in: the microphones used the receivers used the amplifiers used the batteries used

6.  Feedback cancellation enables more open fittings, which can be a major acoustic advantage is more effective in analog hearing aids than in digital hearing aids should be turned off for most fittings due to artifact has not changed much since it was first introduced

7.  Predicted new advantages of digital hearing aids in the future include al of the following EXCEPT: wireless systems integration with other communication systems implantable systems lower cost

8.  Noise Reduction improves speech intelligibility in noise is completely ineffective in all cases enables open fitting by eliminating feedback none of the above

9.  Computer based fitting procedures have resulted in improvements in the evaluation of hearing aids improvements in the fitting of hearing aids Both A and B none of the above

10.  Directional hearing aids have mixed evaluations in real world situations should be recommended for every patient have exceeded expectations for benefit and peformance were more effective before the introduction of digital hearing aids
