A device, called the Mosquito, emits a high-frequency pulsing sound that can be heard by people younger than 20 and almost nobody older than 30. The
sound is designed to so irritate young people, so that after a few minutes, they cannot stand it and go away. It works because the body's
ability to detect the Sonic Deterrent's
frequency, diminishes after 20,
adults are completely immune.
It sounds to
youngsters like a demented insect or a very badly-played violin. It annoys teenagers so intensely
they have to clutch their ears. Eventually they can stand it no longer and have to move on. So far the device has only been tested in one place - the local Spar in Barry (a great place to find hoards of chavs). According to the shop owner the results were instantaneous and there are
now no layabouts to be found.
Howard Stapleton, a businessman and former electronics apprentice at British Aerospace, who was sick of youths hanging around outside his
shop, came up with the idea. Police are backing the Sonic Teenager Deterrent, nicknamed the Mosquito because of its sound.
The £622 black box, which can be attached to the outside wall of shops, offices and homes, sends out 80-decibel bursts of pulsing sounds at up to 16khz.
Working in his bedroom in Merthyr Tydfil, and using his four children as guinea pigs, he came up with a prototype of his device and asked the local shop to test it.
'I got it
so that only my kids hated it and my fiancée and I were completely unperturbed, 'he said.'
We put up the prototype outside the store and almost immediately people stopped congregating.
'The beauty of it is
that the noise does not have to be loud, just pitched at the right level which affects teenagers.'
A Chinese city has introduced a new street-cleaning machine, composed of a
tractor and more than a dozen bamboo brooms. The street cleaner, spotted by
tourists in Qinghuangdao city, Hebei province, China, is a great source of
amusement. 'I couldn't believe what I was seeing, but it was really cleaning the
street,' laughed a passer-by.
More than a dozen brooms are attached to a machine able to turn clockwise or
counter-clockwise. The 'machine' is only able to move litter and dust to the
side of the street, where another person is employed to clear it later, reports
the Beijing News.
Will and Guy ponder, could the street-cleaning machine be used to clear those
pesky teenagers from hanging around street corners?
