There's no such thing as "back to silence" when there's severely reactive tinnitus at play lol - but if it's stable, then yeah, it's probably a very good coping mechanism.
Conflicts with a lot of my approach to living with our condition, so no. Plus it appears that the BtS thing didn't become a "method" until @I who love music made a thread for it in 2014. I'd already had bad tinnitus for 5 years at that point, so there wouldn't have been much incentive for me to experiment with such a thing.
