Not sure if tinnitus but I've heard a ringing in super-quiet environments since I was a kid.
Mid-30s now and a few months back I had a case where the ringing was very noticeable and it lasted a few weeks. I think what set it off was some hearing damage from using high-frequency equipment without hearing protection but it was definitely an experience that I'm not keen on repeating.
Once I noticed that the background ringing was louder than normal I couldn't un-hear it and it was starting to drive me nuts.
