Anyway, the tinnitus does sound somewhat like noise with a peak at a certain frequency. I guess I just think of it as "blood noise". Susanne Vega reference? Anyone? Okay, I'll leave the room now. (great song, check it out)
So sound men turn the volume up, which causes them to get used to the volume and experience hearing damage, which causes them to turn it up more, and the cycle repeats.
P.S. this also applies to classical and jazz. Turn the volume up on those for best enjoyment.
Such self-generated signal may be more annoying than low level external noise.
Over the past summer, it's been mosquito sound for me. There'd be a few, I'd kill 'em, and then sound of the last one would keep 'ringing in my ears' even though I cleared the space of mosquitos.
But hearing is complex. Things like diet, exercize, blood pressure, history of exposure to loud noise, drugs, age etc all play a role.
You don't need the exact frequency really, just create a white noise sample in Audacity. The filtering just helps to allow playing the noise at the lowest overall level possible while still being effective in suppressing the tinnitus.
I think I could have achieved the same filtering using one of those hi-fi equalizer modules that were all the rage in the 80s and 90s.
