When it get's to that point, it can be so hard to live with. Do you know what caused your brothers Tinnitus @norene? I will say this though. I know many people who have habituated who had excruciatingly loud, torturous Tinnitus. They all say the same thing (me included), that when it was at it's worst, it so very bad. But that after they habituated, it sort of just faded out of their awareness. They still hear it, but it stopped bothering them.
