FYI for anyone suffering from Tinnitus, there is new technology that may help. First the University of Michigan has developed a treatment, they are in the process of having a wider test group. Also this company has an FDA cleared device as well.

It is good that the site you referred to advises using this device, and by extension similar devices, only by prescription, under supervision of a certified audiologist. I was curious about how such devices work, and did some digging. The best understanding I came to so far: they could be similar to tooth extraction, or any other surgery that removes a damaged part of human body.
For the background information, you can read
https://health.uconn.edu/meds5377/w...7/07/PALMER-Auditory-Nerve-Physiology-ARP.pdf. Notice the three types of nerve fibers, best described on a slide with caption "At each frequency, auditory nerve fibres differ in their spontaneous rate, input/output function and dynamic range - these covary."
The graphs refer to guinea pig, yet it's been proven that human hearing system works in a very similar way: there are three types of fibers, responsible for transmitting information about very faint, medium-intensity, and high-intensity sounds.
I believe that the fibers responsible for the very faint sounds fail first in modern humans, because we barely have times and places of nearly-complete silence, which would give such fibers a chance to recover. The fibers responsible for high-intensity sounds are much more robust, and I believe that those fibers are the ones staying operational throughout the lives of most people.
A failing fiber - or perhaps a failing neural structure connecting such fiber to inner hair cell - may result in a loss of function, which may be accompanied by a Phantom Limb phenomenon (
https://en.wikipedia.org/wiki/Phantom_limb), auditory manifesting as tinnitus . The neurophysiology of that process in humans is still not completely understood, so please take everything I said with a huge grain of salt.
Still, you may consider discussing your objectives with your audiologist, before subjecting yourself to this procedure. Indeed, if the symptoms are never-ceasing and severe, and there is no hope of restoring the function, it could be the best to "sonically amputate" the most sensitive and/or mid-sensitive fibers. If, however, your case is borderline, and there is a hope for recovery, you may consider giving those sensitive fibers a rest instead.
ADDITION:
It could also be that the sensitive fibers are in effect already "amputated" by prior events, and the procedure works through remapping the sensitivity for medium-intense sounds into the still surviving more robust fibers. In any case, please consult with an audiologist who can intelligently answer your questions about the healing mechanism he or she thinks will be actually working in your case.
And the corollary to it all: please don't try to self-heal with white or pink noise, or with a commodity bedside ocean waves sound machine. You may be healing, or may be conducting an unintended surgical procedure on yourself. At least giving the hair cells and audio nerve fibers a rest from all sounds, even if perceptually increasing a sensation of tinnitus, is physiologically safer.
