It turns out there are a few treatments for tinnitus. Most of these treatments involve sound therapy, where the ultimate goal is to help retrain your brain to tune out the tinnitus. These therapies have been shown to be effective for some percentage of people with tinnitus – probably less than 50%.
So I recently finished it, and put it up @ http://www.generalfuzz.net/acrn/
If you have tinnitus, give it a whirl. It’ll cost you nothing. It may or may not be exactly the same as the $5000 ANM ACRN treatment, but it should give you a good idea what it would be like. I’m always open to suggestions/feedback to improve the project.
