GB, thanks for explaining more about your situation. I've had a hearing problem for years after working on my father's alfalfa mill, right alongside a big diesel engine with no muffler. Dad thought that would cut the power, and wasn't needed. My ears would ring for about an hour after we shut down, but it wasn't "manly" back then to wear hearing protection. Today I can't hear anything above 2,500 cycles, which isn't bad, but I don't hear many of the birds or musical instruments. I dislike being in noisy cafes, bars, etc. because I can't understand anything being spoken. You gave good advice about facing the person being spoken to, and speaking a bit slowly.
I find it interesting how one doesn't really fully value many of the things we have but take for granted until it's lost. Today I have diabetes and as a result I've lost my sense of balance and have difficulty walking. Now it's become important to me, and I know if I don't get the diabetes under control, I'll ultimately lose my feet and perhaps my eyesight. I've already had 5 laser surgeries for the eyes. I'm ok today, and I've got it under control, but walking and seeing are much more important to me today than they were a few years ago when everything worked fine.
GB, I wish you well with your decision, and I think you've probably already made it. I can understand your anxiety about the unknown, but being able to hear is something I don't think you want to lose. I hope that once again you can truly enjoy music!
