In an effort to get around having to turn their phones off in environments where cellphones are forbidden, these crazy kids have come up with the incredible: a ring tone that can’t be heard by most adults.
Per the New York Times:
In settings where cellphone use is forbidden — in class, for example — it is perfect for signaling the arrival of a text message without being detected by an elder of the species.
“When I heard about it I didn’t believe it at first,” said Donna Lewis, a technology teacher at the Trinity School in Manhattan. “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.”
The technology, which relies on the fact that most adults gradually lose the ability to hear high-pitched sounds, was developed in Britain but has only recently spread to America — by Internet, of course.
Wanna see if you can hear this thing?
Did you hear it? Happily, I could.
If you didn’t, go somewhere and get your old ass a hearing aid*, ’cause that shit was fairly loud.
