I have tinnitus primarily in my left ear. After seeing the audiologist I was given a noise generator, basically a hearing aid that make a constant noise but doesn't amplify sound. - I go with white noise but other options are available.
The idea is that it trains the brain to ignore the tinnitus noise. Note it doesn't cure the cause but mitigates the symptom. It works very well for me, so much so that I'm getting a second unit for my other ear. The unit also streams from my phone which is very useful in and of itself.
This is in the uk where they're provided free on the NHS. I guess if you're in the us, then you'll have to sell the house, car and kids too afford the initial consultation.
