[Noisebridge-discuss] Hearing augmentation

[Andrew Cantino]

Hey cyborg and electronics people,

My father is high-frequency deaf.  He used to do a lot of bird watching, but
he has trouble now since he can't hear some of the songs.  I was just
looking at this product: http://www.nselec.com/songfinder.html, but it costs
$800.   It seems to me it's just a band-pass filter for selecting the
frequency range to augment, and then electronics to down-shift that range.
It's been a long time since I did electronics.  How hard would this be to
build?

This might dove-tail nicely into augmenting frequency ranges that healthy
ears can't hear as well.

Thanks everyone!

-Andrew
