If you have tinnitus due to high frequency hearing loss, the ear/brain is trying to compensate. If you get hearing aids, the condition is reduced quite a bit. That has been my experience.
It's working with Firefox at home but with the couple minutes I've piddled with it, hasn't offered any relief. I know everyone is different but what settings do you use?
While I did notice a reduction in ringing in my ears with a hearing aide in both, It also made Everything else so loud and uncomfortable that it gave me a splitting headache. And most of the noises I heard during that were in a closed room with the volume at the bottom. I would have gone completely loco if I had worn them in a public setting. I have an easier time dancin' with the devil I know right now. If it continues to progress, as I've been told it most likely will, maybe I'll try again in the future.
Others may have a better experience or outcome than I did. And to be honest, I really hope they do.
Not an expert by any means. Have been dealing with this for many years but recently went to doctor for hearing aids and the doctor warned me of this problem. But it was my understanding that they could be programmed to prevent this.
I don't guess it helps much that I'm also very sensitive to higher frequency sounds. She said I flinched most of the time when she tested those pitches on me during the initial hearing test. Might be part of my overall hearing malady. And though they did try to make them comfortable for me in the volume and some of the tones I could hear, I don't think, or remember, if she could filter out all the bad and still let in all the good sounds. But, I do remember being there for a while and watching her fiddle with this and that. And in the end, it was a no go.
I'll most likely have another chance to find out in the future and maybe things might be different then.
You have to first match your tinnitus frequency with the "Play single frequency" and then use the "Play ACRN". For example, I have a multifrequency T that centers around 10075 hz that's what I use.
Since my T doesn't sound like a single frequency and more like a range, I use the BB noise setting on this tuner to match my T:

If you experience any residual inhibition, you should be close. The ARCN is based on the same research as a tinnitus treatment offered in the UK... except with the website, you don't have to pay thousands of dollars.
Good luck.
