I used to be a partial with a hearing los. After loosing my sight I became
more aware of the changes in acoustics as I passedby buildings, entering
different hallways in buildings ect. However, the year I came out here to
California, I had my hearing tested in Ohio. I still had the hearing los. I
think that, now that my sight is gone, never to return, I'm paying much more
attention to the things I hear. At least I'm trying to. 73. Doug, N6NFF

Subject: Re: OT: Blind-folding May Improve Hearing
There have been experiments done (including with humans) that indicate
several
things. Congenitally blind folks actually do have better hearing probably
because they are using parts of the visual cortex to help process sound.
Second, blind foldes subjects seem to "listen better" but until recently
there
was no good evidence of a true hearing difference. Third, new evidence is
beginning to come in that prolonged blindfolding may improve hearing. There
is
still a question as to whether this is permanent (it seems not to be) and
how
much improvement there really is.
All told, its a really interesting area.
As an aside, those blinded in later life do show some demonstrable hearing
improvement but not as much as the congenitally blind.
