I read that listening to 40hz might have certain health benefits, especially regarding alzheimers, and lately I've been doing it. It's not especially good at drowning out tinnitus and and I was wondering are there any good specific methods of coping with tinnitus similar to listening to a specific sound? Apart from the usual "just get over it bro" advice.
Also, is it damaging to your ear to listen to 40hz 12 hours a day? Are lower frequencies less harmful than higher?
