Hearing aids help, but DO NOT completely eliminate the tinnitus. I first saw a doctor for tinnitus (didn't even know it had a name at that time) about 1980 or 81. I got my first pair of hearing aids in 1992 ($1,630), my second pair in 2001 ($1,800), my third pair in 2006 ($4,588), and my current pair Thursday ($4,000 after an $800 discount).
It will probably continue to progress. At first it was just ringing in my ears, but not real loud. And now . . . well, imagine that you're sitting under a big tree full of cicadas, so many that their chirp is a steady constant sound instead of a chirp that comes and goes. And imagine that tree is about two or three hundred yards from an Interstate Highway with bumper to bumper traffic going 70 miles an hour 24/7; making a cross between engine noise and wind noise. And on the other side of that Interstate is an old 2 cylinder John Deere (a poppin' Johnny) idling. And then you'll have an idea of what mine has progressed to in the last 30 years.
It's a terrible noise when I get up in the morning, but with the hearing aids and other sounds, I can pretty well ignore it during the day.
