To the best of my knowledge, noise-canceling is accomplished by a microphone listening to ambient noise, and a wave generator creating an exact opposite noise... In order to generate an opposite noise, there would have to be an actual, physical noise against which to generate a canceling noise.

hearing aids <em>out</em> and attend to it. My audiologist said she had
been to really expensive conferences about managing such things, and after
spending lots of bucks, she believes "ignoring it" is the best way to deal with
it. But maybe the hearing aid companies will even be able to address some
of this in the not too distant future.......</font></span></div>

<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Hi everyone,</span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">I wrote a couple of months ago about a new buzz in my
ear</span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">and got a lot of good suggestions. The ear dr.
hasn't found</span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">a cause, after hearing tests and MRI, so it probably is
going</span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">to be permanent. The good news is there was no
reason for</span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">it. Now I need a very well fitted stopper to shut
off the</span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">buzz so I can tune and play again. Thanks
especially to Diane</span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Hofstetter for her big help at the convention and to all
of you</span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">who sent ideas. It was fairly easy to adapt except
for piano</span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">sounds! Wow is it loud when I'm at the
keyboard.</span></font></p>
