Mine is the same. I have no actual confirmation as to why it's there, other than the fact that i just noticed it one day i was staying in a hotel, and it's been there ever since. That was 10+ years ago. I assume it's the "usual" causes, too much loud music and decades of riding my motorbike with crappy helmets, though mine is not caused by hearing loss.
Normally it's just a slight ringing that i hardly notice if there is other stuff going on, but when i get stressed, or slouch in my office chair, it can gain volume in the evening.
I've learned to "ignore" mine. As i'm typing this i'm very aware of it because i'm "focusing on it", but when i'm doing work, watching tv, or even walking the dog i don't notice it. I find it to be the most annoying when i'm trying to listen to quiet tv, or trying to fall asleep.
What i normally do is try to focus on some other background noise. Rain falling on a window, my wife or dog breathing. This usually makes it "go away" for long enough that i'm not annoyed by it anymore.
Fun fact, ANC headphones will make mine disappear which makes absolutely no sense as the noise is non audible, so there's no noise for the headphones to cancel, and yet it goes away, or at least becomes inaudible.
