I've had tinnitus since my teen years, half a century ago. At least, what I normally hear is, I assume, tinnitus, but it comes in two forms. There's a constant sort-of grey noise, not too loud (definitely softer than people talking in the same room), which wavers in amplitude over a sub-second period. The more annoying form is a pretty pure sine wave, much louder, which thankfully is more infrequent. Not really sure if that quieter form is something everyone gets, or an actual tinnitus form. Anyway, after 50+ years, it's not a big deal to me.
