Teen Buzz, A Ring Tone That Only Teens Can Hear!
"A high-pitched alarm which cannot be heard by adults has been hijacked by schoolchildren to create ringtones so they can get away with using phones in class. Techno-savvy pupils have adapted the Mosquito alarm, used to drive teenage gangs away from shopping centres. The alarm, which has been praised by police, is highly effective because its ultra-high sound can be heard only by youths but not by most people over 20. Schoolchildren have recorded the sound, which they named Teen Buzz, and spread it from phone to phone via text messages and Bluetooth technology. Now they can receive calls and texts during lessons without teachers having the faintest idea what is going on."
Recently while listening to the NPR news, I heard about this amazing invention called the "Mosquito." Believe it or not, this invention repels teenagers using a very high ultra-sonic tone that only teenagers can hear, and find annoying. 8O Adults, especially those over the age of 30, cannot hear it and I checked it out myself.  Even more amazing aspect of this invention is that the teenagers have turned this concept around in their favour, they are using it as their cell phone ring tone. Now thanks to the Mosquito invention, the teachers have no idea when their students receive a text message. Now that's smart!
