Re: Inexpensive hearing aids

[Thomas G Brennan <g_brennantg@xxxxxxxxxxxxxxx>]

Barbara, as an audiologist and a piano tuner I am interested in exactly how one
fits hearing aids according to "piano harmonics".  This is particularly true
when looking at different scalings of piano strings as well as tempered vs
nontempered scales etc.  Since the harmonic structure of any note will be the
lesser of the sounds depending upon how far you count harmonics I assume this
involves blocking lower frequency sounds in the aid?

I see that this looks a bit as though I am questioning if you can do what you
claim but I assure you that is not my intent.  I am simply wondering how fitting
to piano harmonics is accomplished and how it can be of use across instruments
and tempraments.
