A question: cheap hearing aid
I know a 93 year old in a rest home. When her daughter threw her out of her house (really!) she didn't get one of her hearing aids. The one she does have is marginal. Buying new is *really* expensive, and she doesn't have any money (related to the process of how her daughter threw her out of the house -- she cried every day for 6 months. No kidding.). I don't have the thousands it would cost to make it right.
Recently we gave her an old cassette player and some cheap headphones. She loves it because she can really hear the contents of the tape.
I'm looking for a simple device, reasonably small, that has a microphone and can drive the headphones with adjustable volume. I'm thinking small (mp3 player size, not hearing aid size). Any ideas?
