Bad tinnitus plus acoustic nerouma keep the ringing loud and clear in my head. Like has been said aspirin and caffeine both will amp up the volume. Noise cancellation headphones with earplugs in airplanes and around loud noises keep some of the wild tones from going in to the painfull range.

tried different "guaranteed" pill remedies and even acupuncture but nothing so far has worked. Chiropractic will help when the volume increases from tmj or your occip being off.
White noise is about the only relief that i have found.
Good luck and let us know if you find a cure.
