Widex Allure: Balancing Feedback Management with Sound Quality

Please note: exam questions are subject to change.

1. Which statement best describes the mechanism of frequency shifting? The frequency of the input is shifted downward to allow listeners with high-frequency hearing loss to hear it. Input above 2.7 kHz is amplified more to provide audibility for listeners with high-frequency hearing loss. The frequency spectrum of the input is reversed to reduce audible feedback. The amplified signal is shifted to decorrelate the direct and amplified signals and reduce audible feedback.
2. How does frequency shifting impact hearing aid sound quality negatively? Shifted sounds are out of tune. Sounds may warble due to the mixing of direct and amplified sound. Sounds become boomy. Sounds become too high-frequency for users with age-related hearing loss to hear.
3. How can frequency shifting be used without compromising sound quality? By applying it adaptively depending on input frequency and hearing aid venting and stability. By applying it only at very low input frequencies. By applying it across all frequencies. By shifting the signal by a frequency above 22 Hz.
4. By how many Hertz does the frequency shift on Widex Allure change the amplified signal? 11 Hz 15 to 35 Hz 11 to 22 Hz 42 Hz
5. Which statement best describes listener ratings of the Widex Allure product compared to those of other products tested? Feedback management is improved relative to other products, while sound quality is unchanged. Sound quality and feedback management are on par with other products tested. Sound quality is improved relative to previous platforms, but feedback management is worse. Feedback management is improved relative to previous Widex platforms, while sound quality is superior to hearing aids from other manufacturers.
