Frequency Lowering: Demystifying the What, When, Where and How

---

1.  What is the difference between frequency translation and frequency compression? Frequency compression utilizes a 'cut and paste' process Frequency translation restores low frequency information, while frequency compression restores high frequency information They are essentially the same thing Frequency translation replicates a HF speech signal in real time to a lower frequency, while frequency compression “squeezes HF information together”

2.  Which of the following would make someone a good candidate for frequency lowering? A low frequency hearing loss A flat sensorineural hearing loss A high frequency, precipitously sloping hearing loss A challenge enjoying music

3.  At the first follow up appointment, if the patient states objection to sound quality because it is too 'different' you should do which of the following? Immediately turn off frequency lowering Counsel on acclimating Administer behavioral validation testing Both B and C

4.  What do the green and yellow shaded areas represent when frequency lowering is being utilized? Source and Target Region Soft and Loud Input Compression and TK's MCL's and UCL's

5.  If frequency lowering is on, and you need to make again adjustment because your patient reports the /s/ and /sh/ sounds are too loud, where is the best place to do this? Quick Fit screen Fine Tuning screen Adjust the Frequency Lowering Gain Adjust the Frequency Lowering Bandwidth
