Exam Preview for 36359: Frequency Lowering Amplification Master Cla

Frequency Lowering Amplification Master Class

Please note: exam questions are subject to change.

1. In laboratory tests, which of the following is NOT a benefit of extending the bandwidth of sound beyond 5 kHz? improved speaker identification improved novel word learning improved speech perception improved spatial unmasking
2. What speech sound class is most likely to benefit from frequency lowering? fricatives vowels nasals glides
3. Which of the following is a side effect of too much frequency lowering? formant alteration; vowel confusions "sh" for "s" confusions reduced sound quality all of the above
4. What is the primary thing to look for when performing probe microphone measures on a hearing aid with frequency lowering? that the "sh" and "s" are at the best possible frequencies that the "sh" and "s" are at the lowest possible frequencies that the audible bandwidth has not been reduced by the frequency lowering that the maximum audible output frequency (MAOF) is as low as possible
5. What is the purpose of Frequency Lowering Fitting Assistants? To eliminate the need to perform probe microphone measures on hearing aids with frequency lowering To empower clinicians by providing information about how sounds are changed with different frequency lowering settings To definitively determine an optimal frequency lowering setting To tell clinicians which hearing to select for their patients
