And expensive.
I am still waiting for a hearing aid that will recognize what is out of your range and modify it to be in your range. That's software doable, isn't it?
I think that’s what they are trying to achieve................
They do it with cochlear implants.............
My hearing aid does a good job. It’s calibrated via computer. When outside “interference” occurs on a regular basis, I run to my “ear guy” and he calibrates it out. Example: paper crinkling drove me nuts, so he took it out. No more excessive paper noise. A noisy room can be a distraction if it reaches a certain level, but that doesn’t happen too often. I’m very pleased with my little “invisible” hearing device.
That would be a godsend.
