I've had tinnitus for over 25 years. I read everything I can on the subject and this is what I've learned.

There is no cure

Tinnitus can and will make you crazy...if you let it.

It is not the same as hearing loss, but it is caused by many of the things that cause hearing loss and can accompany hearing loss. Heredity can make one more susceptible.

Tinnitus is in the mind, not in the inner ear. See post #4.

Others can NOT "hear" what is in your mind (also post #4).

The best one can do is to "control" the tinnitus. And what I really mean is to control how one responds to the phenomenon. I hadn't "heard" my ringing for weeks until I read this thread. I just ignore it. It helps to have some ambient sound to mask the ringing. One of my favorite ambient sounds to mask the ringing is the whoosh of air past my head as I'm riding my bike.

I've been a working professional musician for most of my adult life. While many of the situations I've put myself in professionally have contributed to my tinnitus and partial hearing loss, I've been able to function quite well as a musician. I happen to be a very skilled "listener", and I often hear things that others with perfect "hearing" do not.

My advice:

Accept that you have it and that barring some medical breakthrough, you will always have it. Don't let it drive you crazy! Tinnitus is in the mind. You can control your mind. Relaxation and other concepts will help you to ignore the ringing, roaring, rushing, or whatever noun you use to describe what you "hear". You can learn to ignore it. I did.
