Do new hearing aid users prefer less low- frequency, high-frequency, or overall gain than experienced users?
Keidser, Gitte; O'Brien, Anna; Carter, Lyndal; Froelich, Matthias; Dillon, Harvey (2006)There seems to be a widespread belief among clinicians that new hearing aid users prefer less gain than experienced hearing aid users, and therefore that new users will acclimatize to more gain over time. This belief is ... -

NAL-NL2 empirical adjustments
Keidser, Gitte; Dillon, Harvey; O'Brien, Anna (Trends Amplification, 2012)NAL-NL1, the first procedure from the National Acoustic Laboratories (NAL) for prescribing non-linear gain, was a purely theoretically-derived formula aimed at maximizing speech intelligibility for any input level of speech ... -
