As you probably know, as we age, our hearing deteriorates. It's often in the high frequencies that the loss is most noticeable. Apparently there was even a device developed in 2005 called the Mosquito that businesses could use to deter teenagers from loitering outside their businesses. This website has a recording of a frequency that supposedly people over the age of 25 can't hear. I'm a bit skeptical because I am well over that age and I have to assume that all the years of touring have damaged my hearing to some degree, but I had no problem hearing it. What about you?
