Inexpensive hearing aids



As a professional harpist, I would be very confused if my hearing aid
was tuned to piano harmonics.

I see your point but it does clinically concern me to "not be hung up on the
specifics" when dealing with clients as we're dealing with specific problems.
I've seen you state a lot of opinions and you are obviously working
for the good
of your clients.  Others on the list have asked you for specific data and you
have yet to provide that and now when I have asked you specifically about what
you have stated on the list using specific numbers to justify what you do you
say the specifics do not matter.  Certainly when we treat clients there is a
clinical apsect to things just as there is a scientific aspect.  When I tune a
piano for someine who is an advanced musician I may not tune a purely equally
tempered scale because of what they prefer or the instruments they will play or
the music they use.  However, when I do deviate from  the accepted
norm I always
have a reason for doing so and can demonstrate that reason to any other
professional who asks.  That duplication of knowledge is the reason I have
questioned you and attempted to learn something of your methods only
to have you
tell me that I should not deal in specifics.  I apologize if you have been
offended by my questions but I thought they were quite basic rather than
specific.

 I don't have the equipment to be that exact.  I fit on a general
 principle that keeps in mind that I am working with a musician with an
 expanded representation for sound that is different than non-musician's.
 They may not like the sound of an aid precisely because I haven't matched
 a certain band of frequencies as well as I could if I tried to shift the
 response of the aid off the more traditional "pure tone"
 recommendations.  Pure tones don't occur in nature, so why should we be
 married to the idea that people hear the best when we match the
 prescription formulas or the audiogram to a psychological, subjective
 system.

 I've noticed that some people are spend too much time on the specifics
 rather than the general priniciple.  I'm not concerned with exact
 measurements, but I am concern with the difference in programming that
 may be necessary because of vastly different auditory systems based on
 environmental or genetic influences.

 Please don't get hung up on the specifics, see the point for what it was.
