Don't think I've ever heard complete silence. Even as a kid I had a very small amount of tinnitus. Got much worse after years of excessive audio abuse in my teens and twenties though....
I would love it to stop, in a wistful sighing "what if" kind of a way, but other than that it doesn't really bother me any more. Unless of course I were in an anechoic chamber!
These days I take a magnesium supplement before I do any headphone work, because that has been shown to minimize hearing damage from noise. Vitamins A, C and E are protective too.
