I just started the Soundcure therapy. You are supposed to use Tracks 1 and/or 2, they use the S-Tones that have been demonstrated to reduce or eliminate tinnitus in some patients (4 out of 5 during clinical trials). The other tracks are only masking sounds, which I don't care for - too boring. My initial response was a slight worsening of the tinnitus, this is actually supposed to be a good thing, as I am responding to the S-tones. I plan to really stick to it, and I am somewhat hopeful though sceptical.
