British shop-owner invents a device which emits a high-frequency pulsing sound that, he said, can be heard by most people younger than 20 and almost no one older than 30. The sound is designed to so irritate young loiterers that after several minutes, they cannot stand it and go away.

LOL You've got to be kidding! I'm not that annoying!

Sadly thats old news.

 

He had to take it down after some kid threatend to sue him - a breach of his human rights if i recall correctly.

hahahaha.

 

but its cool now because teens can use the sound as a ringtone so teachers cant hear it ring.

This is why so many kids are coming out of school unable to read or write properly and geographically ignorant.;)

But technology is a whole other new thing to learn about too. It's not all bad, infact I'd say its more good than bad. Kids are still reading and writing, just in a different form/way.

That's no good to employers!;)

It really depends which job. Many jobs these days involve a computer. Where I live adults have to take computer courses before they get the job.

People still need to know how to communicate and interact in a business-like manner. That will never change.;)

I'm very sceptical of this. I work in the hi-fi industry designing and testing loudspeakers. When you design a drive unit, speakery thing, you kind of spec what the frequency range is, for domestic hi-fi you're loudspeakers go from about 50Hz to 15KHz, for top of the range hi-fi systems it goes from maybe 10Hz to 25Khz and thats expensice and uses several drive units for each part of the range.

 

Now mobile phone speakers aren't hi-fi, the're not designed for pitch accurate reproduction of music, on the whole mobile phone speakers are crap and just squawk compared to hi-fi speakers.

 

You know when you're on a bus and someone's mobile phone starts ringing, and they have I dunno, a Coldplay ringtone, you've not going to be fooled that you at a Coldplay concert, its an annoying squawk that sounds like Coldplay.

 

Human hearing for single frequency tones goes up to about 17KHz, this decreases as you get older in your twenties, to around 13KHz. So for this device to work, your standard mobile phone loudspeaker needs to reach around 15KHz.

 

I don't believe it.

No, lazyness is...before cell phone were invented kids didnt pay attention much in school....its not the technology but the person. some people just wont or dont want to pay attention in school;)

lol it's not just for any kids, it targeted kids which hang around shops late at night (usually, although not always) and cause trouble. the shop nearest me had kids jumping on their roof and throwing stuff at customers walking in and out of the shop.

Correct - it's an anti-chav device!!

Playing Cliff Richard would probably have the same effect, though!:P

It works because they featured it and tested it on the gadget show last year.

 

One shop in andover plays classical music outside to get gangs to move on.
