Why was it created and who is profiting from it now?

www.eschoolnews.com/news/showStory.cfm?ArticleID=6350Teacher-proof ring tone latest 'teen buzz: A technology using ultra-high frequency sound to drive teenage loiterers away from shopping centers in the U.K. has been hijacked by tech-savvy teens to create an inaudible cell phone ring tone. Students are employing the technology to surreptitiously use mobile phones in class by creating ring tones that most adults cannot hear.

Jaga Leave it the Britischers to come up with some thing that will back fire  or other wise called, The Mosquito device. Uses Blue Tooth Technology in high Frequency sound that most adults have not the ability to hear. the teens of today, will be tomorrows largest consumer of hear aid batteries. It is funny, Carl had the same idea I had as his url was that of mine. for I had no idea what you were talking of, and as thus, to look up with a little sweat on the Internet. Gollies, now to think of this for a moment, an opportunity has been arisen! Now if all these kids ruin their hearing being silly, the energy cell business should be the next horizon. Well, it was an idea {and I heard or read some where, German people have no sense of humour} {or was it no sense!} Charles |

Carl is a winner because he was the first. Charles, thanks for the comments. You can try to listen to some of these high frequency sounds but they are not very comfortable to listen! Check wikipedia en.wikipedia.org/wiki/Mosquito_Ringtone |

I tried the sound which is advertized in Wikipedia at the end as a survey from Mediatokyo and I still could hear it but I had to put the volume up.

I can hear up to 19.9 if the computer is working properly. Some of the lower frequencies seem to drop out, others are clear with volume turned up full. I try to wear ear plugs when hammering inside or lawn mowing - or flying in small aircraft. Ear plugs are also the greatest secret for a pleasant flight on an airliner. When kids are screaming or you are just out of sorts, ear plugs cut out the worst and make life quite bearable!
I left my teens about 40 years ago.

I heard faint sound as I have nerve deafness.
