Like many on here, I've been dealing on and off with moderate Tinnitus for decades due to a variety of reasons. (loud music, stress, age, etc) I've read a lot about the various treatments but have never tried any. This one sounds promising and is the only treatment with FDA approval (based on extensive clinical trials). It uses a combo of sound masking (headphones) and electrical impulses (tongue). Basically, the intent is to distract/disrupt the normal process of the brain filling in the missing sound spectrum (due to hearing loss usually) that the brain is reproducing on its own. (that's the theory) https://www.lenire.com There as some informative videos on the site about the FDA trials and how the device works.
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.
