I haven’t had this issue but hear me out. I have not googled this or have ANY medical experience but will share my wife’s experience.
My wife has it really bad for the last 30 years. 5 years ago she caught a virus when we were in Mexico and lost 70% of her hearing in one ear. She got hearing aids (for both ears) for that ailment and something strange happened. She could hear more and it acted like “white noise” and caused the ringing to lessen. She said it temporary but when it starts to come back, she wears her hearing ads for a while and it helps.
I don’t know how this would work medically speaking, but my wife has had serious tennitis for decades and swears that it has helped.
