Exam Preview for 39113: Maximizing the Efficacy of the Widex Sound

Maximizing the Efficacy of the Widex Sound Assist™ Remote Microphone

Please note: exam questions are subject to change.

1. What are the negative effects of talker-listener separation? decreasing signal level contamination from reverberation and noise reduced signal-to-noise ratio all of the above
2. What talker-listener (T-L) distance was selected to approximate real-world situations, such a classroom or long conference table? 3 ft 7 ft 13 ft 18 ft
3. A study design that evaluates performance at varying distances between the talker and remote microphone: can inform on how far the remote microphone may be placed from the talker to still expect benefit can avoid the risk of over-estimating benefit can improve understanding on how patients can be instructed to receive the most benefit from the remote microphone all of the above
4. What is the measured SNR improvement for the remote microphone used in partner mic mode at a distance of 3 inches from the source (like wearing it at the collar)? 6 dB 11 dB 14 dB 20 dB
5. In which of the following conditions would a remote microphone be most effective? close proximity between the remote microphone and target source (talker) minimizing noise surrounding the target source (talker) use of remote microphone adaptive mic functionality all of the above
