My first reaction to this was, "this is dumb and annoying", and then I played with it for a few minutes and found a set of levels that were causing my symptoms to briefly go away. It still isn't perfect, but a combination of Steve Seq and Pulses High creates "gaps" in my tinnitus, where my brain seems to "forget" about it briefly and I don't hear it. But then it comes back a millisecond or so later. I don't think I could get work done with this on all day, but it has more effect on my symptoms than other websites I've tried. It's really interesting, like there are brief (millisecond) periods of no tinnitus. [I've had it in my left ear for probably 35 years (I played in a punk band in the early 80's with no hearing protection but it didn't show up until a decade later).]

Keep at it, I think you're on to something!
