I’m sorry I only have time for a bookmark now, but I am 65 years old, have played rock and roll all my life, and have suffered quite a lot of high frequency loss. I have found high-end hearing aids to be helpful, in fact they have completely changed my life at work and at home. I promise to write back in a day or so with useful information.
I see that many others have provided most of the info I was going to write :-) FReepers are awesome.
When I finally admitted to myself that I was missing huge amounts of conversation, and sounding like a dummy ("What? What?"), I checked with my insurance and was fortunate to be able to spring for some high-end digital (DSP) programmable hearing aids (Oticon Alsa 2) which have saved my marriage and my job. That is no exaggeration. Seriously, what is that worth?
Tell everyone around you -- especially young folks -- that hearing has to be protected around loud noises. I was told when I was a kid but I didn't listen because I wanted to play loud rock-n-roll. Oh well, live and learn; thank God for digital hearing aids. Don't bother with the cheap ones. I tried them, I tried the "amplifiers", all that. They're cr@p compared to real hearing aids.
Good luck and God Bless.
