Sadly, I have all of the problems in that article. My left ear isn't too bad - just slight loss in the higher frequencies, and that's probably the result of drumming. My right ear, however, is terrible. I had a viral infection of the inner ear (didn't hurt, I didn't even know I had it) that destroyed most of the auditory nerves. I can't even hear on that side with the type of hearing aid that transmits sound through bone. Plenty of tinnitus on that side, though.
Soooo, I know what it's like to be impaired, even if mine wasn't caused by loud noise. Take care of your ears!!!
