Research QuickTakes Volume 2: After the Hearing Aid Fitting - Important Considerations

---

1.  In recent research, what percent of patients reported “no difference” when gain in the high frequencies was changed by 8 dB (both above and below programmed target gain)? 10% 20% 30% >50%

2.  In research with trainable hearing aids, when the subjects were fitted 6 dB below the NAL targets, they tended to train the hearing aids to which targets? 3-4 dB above the NAL targets About equal with the NAL targets About 5-6 dB below NAL targets 10-12 dB below NAL targets

3.  Acclimatization to hearing aid use might result what range of improvement in patient’s SNR for a speech-in-noise test according to recent research? A 7-10 dB improvement in SNR A 5-6 dB improvement in SNR A 2-3 dB improvement in SNR No change in SNR following acclimatization

4.  What is an example of machine learning in modern hearing aids? Modulation-based digital noise reduction Expansion Own voice processing Wide dynamic range compression

5.  During the home trial, it was determined that the Signia Assistant was used the most in which listening situation? Listening in quiet Listening in noise Listening in speech-in-noise Listening to music
