Phonak SoundRecover: Advancements in Frequency Compression

---

1.  The main goal of SoundRecover is to: maintain normal tonotopicity of the cochlea make high frequencies less harsh extend the perceptual bandwidth of hearing aids improve initial acceptance of hearing aids none of the above

2.  The following tests have been found to be sensitive to the effect of frequency lowering: UWO Plurals Test The Phoneme Perception Test (PPT) CNC word recognition Aided vs. unaided high frequency thresholds All of the above

3.  A risk of very strong SoundRecover settings was: too much high frequency audibility distortion of vowel formants high noise floor poor spatial awareness upward spread of masking

4.  One electro-acoustic stimulus that is helpful in fitting and fine tuning frequency lowering is: MPO sweep insertion gain ANSI bandwidth test calibrated /s/ and /sh/ stimuli soft recorded speech

5.  Fitting logs show that SoundRecover was activated mostly for: infants all children ski slope hearing losses it was usually deactivated Sound Recover is applied with similar frequency across all age groups

6.  Clinicians reported the following benefit(s) of SoundRecover: better detection, distinction and recognition of high frequency phonemes better access to environmental sounds improved vocal quality reduced feedback all of the above

7.  With SoundRecover 2, frequency lowering is applied adaptively: between the upper and lower cut off frequencies between the upper cut off and the maximum audible output frequency at the intersection of happy and healthy in the linear output area none of the above

8.  The lower cut off frequency is based on: the bandwidth of the hearing aid the highest audible frequency for 80dB inputs the amount of high frequency gain that can be prescribed without feedback the average level of /s/ at 6kHz None of the above

9.  Which of the following are part of the philosophy behind SoundRecover 2: maximum stimulation of the auditory nerve protection of the low and mid frequencies extension of frequency lowering benefits to more severe and profound hearing losses all of the above none of the above

10.  In SoundRecover 2, mid frequencies are protected because: an adaptive compression scheme is used compression is never applied to the mid frequencies very low knee-points are applied compression is never applied below 3kHz compression is applied equally across the entire frequency spectrum
