Nope, but I know a co worker that has it. He was former military who maintenance artillery and tanks so that might have something to do with it. Supposedly, it takes time before one notices hearing damage that could have occurred years earlier in life (he is around 65 now and only recently noticed ringing in ear). Says it drives him crazy at nights when I guess he notices it the most. He has to get up from bed and do something to distract himself from the sound since he can't sleep too well while it rings.
I believe my dad has a low hum in his ears (he was artillery in Vietnam).
