Introducing ReSound Sound Shaper: A Unique Implementation of Frequency Compression

---

1.  How many setting options are there for Sound Shaper? 8 4, including Off 5 None of the above

2.  The default setting for Sound Shaper is “Off” because: In most, or many cases, you will be able to provide good audibility without activating Sound Shaper For mild hearing losses or reverse slope losses, conventional amplification can be expected to provide good audibility for a wide bandwidth Both A and B are correct None of the above

3.  The criteria for recommending a Sound Shaper setting is based on: The age of the hearing aid wearer The PTA (Pure Tone Average) Speech-in-noise test results The audiogram severity and configuration

4.  Why is it particularly challenging to provide audibility for high-frequency fricatives? Because conventional amplification can limit adequate access to high-frequency fricatives due to the receiver response Because high-frequency fricatives have little importance in speech Because cochlear “dead regions” make amplification ineffective Both A and C

5.  Frequency compression is: The only way to make high-frequency fricatives audible An alternative tool for improving high-frequency audibility for patients when conventional amplification doesn’t do an adequate job A bad idea because no audibility is better than audibility at “misplaced” frequencies Appropriate for all patients

6.  Sound Shaper: Is ReSound’s frequency compression feature Uses a non-proportional approach to frequency compression Can improve audibility of high-frequency speech cues Maintains the best sound quality possible in a frequency compression technique A, C and D are all correct

7.  In developing Sound Shaper, objectives included: Distinct settings that could provide benefit Preserving sound quality to the extent possible Simplifying fitting of the feature All of the above

8.  If the audiogram has a slope of 10 dB or greater per octave and the slope begins at 4000 Hz or higher, which setting is recommended? Moderate Mild Off Strong

9.  Which of the following statements is true about frequency compression? Normal hearing listeners are not sensitive to the effects of frequency compression Hearing impaired listeners may find a range of frequency compression settings distinguishable from the unprocessed sound in terms of sound quality Both normal hearing and hearing impaired listeners prefer no frequency compression or moderate frequency compression settings to strong frequency compression settings for music None of the above

10.  A cut off frequency of 2500 Hz and compression ratio of 2:1 is consistent with which setting? Strong Off Mild Moderate
