Hearing aid technology has indeed progressed at an amazing rate in the past few years and continues to do so.

Each aid now has two microphones in it plus a computer chip that can be programmed in various ways. Last time I checked, there were 6 or 8 manufactures of aids but only two chip makers. Mainly what you're paying for (if you're paying) is software - the higher the price the more things can be programmed in.

Last time I had my hearing aids "tuned up", I put on headphones and indicated which tones I could hear. They were at various frequencies and volume levels. Took about 2 minutes. Then she took my aids and set them in front of her computer and, after a couple of clicks, they were re-programmed to be optimal for my current hearing deficiencies.

Amazing!
