The USAF caused mine, Jet Engine mechanic. After 45 years of the Tinnitus getting louder and louder, I contacted the VA, and they qualified me for a $123 P/Mo VA Disability and hearing aids, as well as all the batteries, tubes and tips needed. The Hearing Aids are the newer behind the ear, programed kind, programed for just your specific regions of hearing loss. I'm hearing thing I had not heard in years. When they are in, the Tinnitus is "subdued", but still there. Unfortunately when you remove them to sleep the Tinnitus is still there. It's hell some nights when you wake up to relieve yourself at 2 AM and then can't get back to sleep because of the @#$%@# ringing in your ears.
I can hear much better, the Tinnitus is "reduced" in the daytime, the $123 buys a lot of ammo. don't have any other choice but to live with it.
When I was being fitted with my hearing aids, I asked the Dr. about Quietus, and she said to put it in the category of "Spray-on-hair".
