My tinnitus has been incredibly near silence since my acoustic trauma. Even if it is still there, loud noises no longer bother my ears and I rarely suffer from spikes, which I am thankful for. I have one tone in two ears when I used to suffer from seven in one and four in the other one - and it is no longer reactive. I no longer suffer from ear pain, but this doesn't mean I test the limits either.
Are you participating in the trial? Can I ask where you are located?
