I too have the high pitched constant ringing in my ears. Sometimes I think I hear something and I physicaly move around the room trying to pinpoint
the sound but mostly I can not find the origin. I have tried shutting off the power to the house even unplugging the phone from the wall still I can
hear the ringing, sometimes I think it is the neighborhood lighting but I have hiked up the hills where there are no lights or powerlines and I still
have the ringing. I do not know but I thought maybe it could be some sort of sound the body makes, you know when your ears 'pop' when there is
elevation change or in deep water the ringing gets muffled until you yawn or get out of the water. Interesting how it is linked to high blood
pressure next time it is real loud I will check my pressure and see what it is. It deffenately gets loud when you hear planes or been to a rock
concert or listen to big fireworks but I think for the most part that is temporary hearing loss, who knows maybe the hairs in our inner ears are
humming to the tunes of our heartbeats and electrical brainwaves.

One thing I know is that asprin makes it worse. I
get past it by staying busy, then I forget about it. Now you are sensitized to it and ignoring it is tough. Keep searching.
