1.  Why is the Widex tinnitus algorithm unique? It offers broad band and narrow band noises as masker It uses fractal tones as a stimulus It offers an integrated approach to tinnitus treatment all of the above

2.  What is not true about the Widex HD Locator directional mic system? It has an adaptive directional microphone in each of the 15 channels It reacts differently to speech and noise signals presents from the back/side It switches from an omnidirectional program to an adaptive directional program It switches from an omnidirectional mode to an adaptive directional mode

3.  ReSound offers the following wireless solution: 900 MHz radio frequency 2.4 GHz radio frequency infrared microwaves

4.  Which of the following is true about ReSound Bandsplit Directionality? provides directional benefit used as omni directional processing to overcome directional low frequency roll off both A and B None of the above

5.  Which Unitron feature would you adjust in a patient is having difficulty understanding speech in background noise? Antishock Phase Canceller SmartFocus Occlusion Manager

6.  The Oticon approach to directionality is characterized by: The use of directionality in only high level sound environments The use of directionality only in the low frequencies A direct test of S/N improvement to drive automatic mode switching The use of multiple programs to implement different directional modes

7.  The advantages of using Oticon's Near Field magnetics as the wireless approach include: Lower power usage Smaller component size High speed data exchange all of the above

8.  Which Unitron feature has the expected benefit of improved speech intelligibility in background noise? Automatic Adaptation Manager Flex uDirect Speech Zone 2

9.  Speech in noise improvement from Phonak's Roger pen technology for the severe to profound category is attributed to what feature(s) Beamformer microphone Noise reduction signal processing Accelerometer All of the above

10.  As a result of Phonak's Binaural Voice Stream Technology, StereoZoom beamformer technology places speech or signal of interest in front of the listener at what angle? 60 degree in front center 30 degree in front center 90 degree in front center 45 degree left and right of center
