Tell me about it. When I was around 20 I had to have a TV repaired because something came loose and the flyback transformer was howling at its 15.734 kHz frequency. The old repairman couldn't hear it even though I could barely stand to be in the same room with it. I doubt I could hear it anymore.
I hear a nice 10k tone all the time thanks to car races, firing guns, unmuffled lawn mowers, machine shops, power plants, factory floors, fireworks, exploding bicycle tires, homemade explosives, and anything else that could assault my tender young and unprotected ears. The stupidity of youth!
