Do any hearing aids frequency shift, or compress the frequency scale (e.g. just higher frequencies compressed down to lower frequencies so that voice tone stays constant and sibilants get shifted down into hearing range).

yes, I know Phonak hearing aids were doing that since about 2012. For some of our more severe hearing impaired patients it was a noticeable improvement in speech comprehension.
