I used to use hearing aids when I was a kid, but after school I gave up on them because they were so annoying. If it wasn't the snap-crackle-pop being amplified to the point of drowning out everything else, it was the earpieces filling up with wax within minutes.
I am able to use a cellphone when the volume is turned up. I just posted a message about the availability of loud bluetooth headsets, and now I have a related subject. I read, a couple of months ago, about using a cell phone as hearing aid processors, by running an application on the phone, which would receive sound via the mouthpiece (or via phone signal from tower) process the sound as needed (perhaps using built-in DSP), then send it to an amplifying (and perhaps noise-canceling also) headset. I just saw an article recently about this kind of app:

My phone is getting due for replacement, so I could be talked into an Android phone or Blackberry. I'm not interested in iPhone; I want something with real buttons -- my ears aren't the only things that are slowly failing.
Of course, better yet would be a Java app or whatever that could be modified to run on most Java-capable phones. :)
Thanks!
