I dunno if this would work for me.
My tinnitus is caused by cervical stenosis. Rotating my head makes the noise louder or whiter, and changes the pitch.
With a little movement coordination, I could write and perform my own music in my neck.
Potential relief for tinnitus?
Just came across this article. While I don't suffer from this myself, I have read posts from others who do. Hopefully some good will come out of this discovery.
