But Can You Hear Me Now … Grandpa?
Last fall, a device called the Mosquito was introduced in the UK. It's designed to deter gangs of teen loiterers by emitting high-frequency sounds that are harder for older people to hear. (BBC story)
Flash forward to today's Chicago Tribune:
In that old battle between young people and their keepers, the young have found a new weapon on the cell phone front: a ring tone that many adults cannot hear.
"When I heard about it, I didn't believe it at first," said Donna Lewis, a technology teacher at the Trinity School in New York City. "But one of the kids gave me a copy, and I sent it to a colleague. She played it for her first-graders. All of them could hear it, and neither she nor I could."

Right on! Great! All the power to them. I am an old fogie who hates the sound of the endless ringing of the phone. “Hello, is Chelsea there? Is Josh there? Ring, ring ring ring ring, it is enough to drive you mad. I wish they would put that option on regular house phones as well. mick http://rockwatching.wordpress.com

Got your comment on my site. I was a big D&D player when I was in my teens, that was back about thirty years ago. Nobody had any idea of what we were doing back then, they thought we were devil worshipers or something. Parents wanted to take me to a psychiatrist. I remember the first books out on D&D and how it evolved. We had what we called “The Blue Book” which was replaced by the Greyhawk series, and then the big kicker, the arrival of the “Monster manual” . Mick http://rockwatching.wordpress.com
