A few words, not so much to say indeed.
Why something about tinnitus?
Because I have it, since 1990 and I’m not gonna lie about it: You too, are not gonna heal
You could and should just cover it, #masking is the only one suitable strategy.
Just buy a player, or use Your phone and download everything related to environmental and natural sound: rain, sea, wave, wind, insects (yes), waterfalls
What kind of tinnitus is bothering You?
You can find your frequency level here: when the weird sound is covering and matching Yours, here You are.
