anyone know where to find frequency response/data or spec sheets for specifically widex momet sheer and phonak audeo lumity S, M and P receivers? Google is NOT helpful, and this info isn’t easy to obtain, or seemingly so
Look on the Phonak pro web site and find the data sheet for your model.
[For Professionals - Phonak Audéo Lumity hearing aids | Phonak27]
It shows the frequency response for various receivers. For example, for the M receiver it lists a frequency range of < 100 - > 8000 Hz. The sheet also shows plots of parameters such as acoustic gain. It also lists distortion at a few frequencies.
Oticon has similar info available and lists 100 Hz as the low frequency limit. I haven’t looked for Widex info.
