Tinnitus is what you are experiencing; perceived sound with no external stimulus provided.

There are a good amount of treatments for the tinnitus, but they aren't really statistically reliable.

The most interesting I found: Berthold Langguth, German neurologist would apply an electric or magnetic current for stimulation over the head of the patient to reduce ringing sound.
Or..
Direct stimulation of auditory cortex by implanted electrodes
Or...
* Low-pitched sound treatment has shown some positive, encouraging results.(UC, Irvine press release)


There's also surgery, but that would result in unilateral(you left ear) deafness or hearing loss.

I would go the electrical stimulation route for treatment, try to find a doctor nearby that specializes in that, and see how that helps your tinnitus.

ps..There's also a stat that says after 30 years of having Meniere's disease, 50% of patients have it become a bilateral disease (both ears)...hopefully that won't be that case
