One thing I've never read about is the different levels of Tinnitus. By looking at commercials, one would think that to have Tinnitus is akin to having a high-decibel audio tone ripping through your head 24/7. And maybe, for some, it is. I've had it for decades but it's always been a very low-level type of ring. So low that it isn't audible if ANY audible sound is present, such as conversation, TV. or audio appreciation ;) is happening. Only in moments of total silence, like when I go to sleep, is it noticable to me. But not ever to the point of hampering me, I sleep like a baby. Would I rather not have Tinnitus? Of course, but I guess I've been lucky.
I'd be curious to hear from other audiophiles as to the 'level' of their affliction.
