That's actually not tinnitus but (from what I've been told) cochloreal hyperacusis, another form of hearing damage.

I always have that, but I only hear a random high pitched tinnitus noise in one ear, rising and falling in volume for max 10 seconds, about once every few months.

I can still hear old CRTs in my forties, although it's less maddening now. They had those mosquito devices, that are intended to repel kids, for a while at a shopping mall near me. They repelled me very effectively as well.

A friend once thought it was funny to try the 15.000Hz silent ringtone on me, although I had told him not to. It made me react without conscious input and I nearly broke his phone.

I get these, too. I just looked it up, and it's called "Sudden, brief, unilateral, tapering tinnitus (SBUTT)." That's quite an SEO-friendly name.

CRT's and coil whine used to drive me crazy as well. It was the number 1 factor in any electronics purchasing descision.

Holy crap! I'm not alone! And now I have a name for it. They've always freaked me out and I don't even know how to describe it to people.

I assumed everyone has that.. and that its the last output of a receptor dying.
