Thank you. According to the doctors I've been to I don't actually have any hearing loss or damage, so I'm not sure if we have the same problems.

BUT I have spent most of the time trying to mask the sound - mostly by being outside among traffic most of the day, though it always comes back in the evenings / mornings. Then last night I decided to try to stop avoiding it, since without actually confronting it I'm not sure how my brain can get used to it. It was maddening, it does drive me crazy still, but somehow it's less exhausting than the constant fight against it. So I think your advice could still be valid in my case. We'll see. Thanks again for your response.
