Don't think about it. I don't notice mine unless I think about it, then it drives me nuts (short trip). It sounds like down at the pond at night in the summer, crickets, frogs, hundreds of them all at once. Other times it's like compressed air blowing off.
I wouldn't hold much hope for a cure. From what I understand, your inner ear is filled with fluid and is lined with little hairs, each with a nerve ending. Sound vibrates your eardrum which is connected through tiny bones to the inner ear. When the inner ear vibrates, the hairs wiggle creating signals which travel to the brain and get interpreted as sound. Beginning about age 50 for men, the hairs begin to die. The short ones, which pick up the high frequencies, die first. The brain expects to have the signals within a certain range and will adjust the gain accordingly, sort of like automatic gain control. Large signals are attenuated and small signals are amplified. This causes hearing to be logarithmic, so for a sound to double in percieved volume the power must be increased by one order of magnitude (10X).
Anyhoo, tinnitis occurs when the brain begins to receive smaller and smaller high frequency signals so it turns up the gain, so to speak, trying to maintain the signal levels. When the high frequency gain increases, random signals begin to get amplified and interpreted as high frequency sound. That is tinnitis. It is similar to turning the gain way up on a PA system and getting feedback. That's the way I understand it anyway. The doctors out there may have a better or different explaination. What I'm getting at is if the nerve hairs are dead, I don't see how they can be brought back, although I would love to hear of a cure.
I have the Calibra Free behind the ear hearing aids and they do a good job of amplifying high frequencies but it ends up raspy sounding because of my hearing loss. My comprehension is down to about 85% and hearing aids don't help much with that, they just make things louder which may help mask your tinnitis. I have a friend who keeps a small fan running in the bedroom at night to help drown it out.
I have heard of people with hearing loss being able to hear their blood pumping, especially when they lay their head on a pillow. I think this may also be a result of the increased gain.
I did have one doctor tell me they didn't know what caused it but they do know Aspirin makes it worse.
