It’s a good question and the jury is sort of out on that. That is what tinnitus is like, yes, but on the other hand, in an exceptionally quiet environment it is possible to hear things like the blood rushing in your ears - and tinnitus can also manifest as a roaring sound. I think it is fairly normal to hear something in very quiet environments, even if you don’t have tinnitus. With that said, my advice to you is, don’t do that. ;) Maybe you have it, maybe you don’t, so probably best to just ignore it, because it’s not a problem unless you start paying attention to it. Interestingly, having this conversation on HN has made mine more noticeable, so, I better move on too!
