Perhaps.@kelpiemsp mentioned he felt less sensitive to noise after neuromodulation, see the Minnesota thread.
Perhaps we can only be helped by restoring hearing in a damaged area AND by stopping the brain from becoming hyperactive and turning the volume up.
There is still a lot to be learned...
I personally think hearing regeneration and neuromodulation are both part of the tinnitus puzzle. We may even need both to make a lasting cure.
One of the things that worries me and I wonder if it is a concern to others is how fragile and complicated the ear is, especially the cochlear nucleus (region). In saying that, I am especially talking about related nerves. Then you have this complicated relationship with the brain. Our understanding of it is limited and there is a lot of guess work and theories.
How much do these scientists and researchers know? Can they learn significantly more following the clinical trials? Are any breakthroughs forthcoming, any that would help with tinnitus? :-/
