I have tinnitus from years of shooting without hearing protection (.22 is quiet enough you think you don't need it), along with years of working with power tools and construction.
It actually took me quite a while to realise that it wasn't normal. I wonder how many people are in the same situation and have tinnitus, but don't realise.
Oddly enough, it doesn't really bother me. I've just readjusted my baseline of what silence is to me.
Same exact situation here, and for the same reasons. I was young and stupid and worked as a roadie for a rock band, and numerous other very loud activities (engine room of a tugboat, for example) with no protection. I have constant tinnitus now, but like you it is just sort of the background hum of the universe for me. I suspect that any process which causes you to focus more attention on it will not be helpful.
I've had tinnitus for years but only recently realized that I had it. I always thought it was normal.
I'm in the same boat where it doesn't really bother me. All I need is a small amount of ambient noise and it's a complete non-issue. A simple ceiling fan suffices for me. It only bothers me when I'm in complete silence, which basically doesn't happen.
