I did not know that some people have permanent tinnitus! I imagine that could get pretty annoying, but I suppose like anything else after awhile you just get used to it.
Well, you do learn to ignore it at times, but it's hard. I found out my son is actually helping another guy do some programming work for a trial study on tinnitus elimination. They seem to be focusing specific frequencies to permanently cancel out the damage. I need to check into it more and see if I can be a test subject.
