"Tinnitus Retraining Therapy" was invented for tinnitus obviously... accidentally, it was found to treat hyperacusis.
Basically, I wear devices that look like hearing aides all day. They do nothing but emit broad-band sound (sounds like static) at adjustable volumes. Exposure to constant, quiet sound desensitizes your ears/brain. When I went in, my tolerance level was 60 decibles (normal speaking voice levels- any sound above this was painful). A month later, it had gone up 5-10 decibles. After about 6 months it was ~90 decibles. The next time we met, it was 105 decibles (normal)
However, though my levels are testing as normal, in reality it is not completely there. I still have extreme negative reaction to loud souds (like loud music, car horns).
Also, sometimes I have "setbacks" after hearing something loud.
In fact, for the past week, my sound tolerance has decrease and I've had a lot more ear pain after a *#@! bagpipe player parked himself near me a week ago.
Like the article said, sound therapy does not help everyone; no one knows why. Some people never improve, though it helps most patients (it saved my life).
The audiologist is now attempting to treat my tinnitus with TRT. Basically, I tune the sound generators so the noise emited is slightly below the noise of the tinnitus, and the two sounds blend. Over a long period of time, this supposedly trains the brain to ignore the sound. She said if it is successful, 90% of the time I will not hear the sound, and the times I do hear it, it will not bother me.
I do not know if TRT will help me with learning to ignore the tinnitus. I can defintely say it is less annoying when wearing the generators (which I do all the time).
I paid $3000 for the devices and treatment. I did it for the hyperacusis treatment (which worked very well) and hope I will get some benefit out of the tinnitus treatment.
If you suffer from hyperacusis, by all means try it IMMEDIATELY.
If you have tinnitus that annoys you, I would say it very well might be worth a try. I'm not sure how effective it will be for mine.
If you don't have either, buy suppressors and never shoot without them.
What a nightmare.
