I'm 45 now. I first acquired tinnitus at around age 16 or 17, when I went to see Ozzy Osbourne's "Bark At The Moon" show in NYC. It was my first concert and I got to leave with a reminder of it for the rest of my life.

I didn't know about tinnitus or wearing earplugs then.
From the age of 19 I became an avid motorcycle rider. I crossed the U.S. 4 times and rode from California to Alaska on 1 (amazing) trip. All of the road noise from going at high speeds aggravated my tinnitus.
Playing in bands, seeing live shows, etc. has further aggravated it to where now I have a VERY loud ringing, especially in my right ear and ringing in my left ear as well..
However, I suffer no hearing loss (according to my hearing tests). I just have the constant ringing in my ears.
To be honest, I just don't think about it. It's rarely an issue. It sucks, and I wish it wasn't so, but on a conscious level, it doesn't bother me.
I've often wondered, however, if it affects me on an subconscious level. Meaning, my world is never silent. When I'm in a quiet room, asleep, meditating etc, my brain and body are constantly subjected to this noise. Does it affect my sleep? Is this why I wake up feeling tired most times?
I wonder.
