I think my tinnitus is so easy to ignore because it's perfectly even and at extremely high frequencies I probably can't even hear any more. Which is what I assume the cause is.

Honestly I didn't think I actually had tinnitus because I don't notice it for weeks or maybe even months at a time, at least not for more than a short moment, although I've have it as long as I can remember. It's not all that loud, but after concentrating on it for a while it's been there constantly and consciously for a good 10min already and it's not going away!
