I don't think it wouldn't be a problem (not that I'm a scientist).
I experience my tinnitus as a brain related thing. At the time of onset it was a faint small tone in my right ear. In the following period the tone changed and now it's more like my brain is hissing ultra high tones. My brain is making this shit up and it really feels like neurons have become hyperactive and started firing at random. The tinnitus tones I now have don't have anything in common with the tone of initial onset.
With that in mind I totally believe that something like MuteButton which disrupts the firing of the neurons and lets the brain "relearn" its normal pattern could benefit me. I feel like the frequency of the tones is not the key, it's more the disturbing effect in combination with the stimulation of the nerve to let the brain STFU!
