Chony,
Hearing loss is a serious problem, particularly among musicians. Gene hit the nail on the head. I have permanent Tinnitus from the lack of hearing protection when I was a kid in the U.S. Navy. Back then there was no such thing as hearing protection devices for those of us manning anti-aircraft guns. When those 3-inch diameter, 75-pound shells were fired the entire gun crew experienced immediate hearing loss. The loss lasted for two to three days at a time, and the recovery was subsequently diminished with each ensuing exposure. My brother-in-law, who served on the same ship with me, has the same problem.
Good Luck,
Gary
