I'm getting the sinking feeling that my hearing (like all my relatives before me) is getting crappier with each passing year.

I can't be bothered with the expense and inconvenience of a fulltime hearing aid.

I figure it shouldn't be too hard for me to hack a linux handheld into "as needed" hearing assist. It would be a nice opportunity to tinker with some noise reduction Dsp type algorithms.

Any recommendations on suitable linux handheld? Requirements....

* Decentish sound card / ADC / DAC.

* Fair amount of grunt to slurp a packet of better than CD quality sound samples, massage it in real time and spit it out the headphone socket.

* Physical form factor that can be left "on" and in a pocket.

Any recommendations on a microphone that will collect meeting sized conversations?


Anybody know of anybody doing a similar project?

Thanks...
