UK Commissioner Seeks To Ban Ultrasonic Anti-Teen Device
mikesd81 points out a Times Online article that discusses the legality of the Mosquito sound device, which is used to annoy and drive off younger people with sounds that are too high-pitched for most adults to hear. We discussed how annoying this device can be a couple years ago. From Times Online:
"Sir Albert Aynsley-Green, the Children's Commissioner for England appointed to represent the views of the country's 11 million children, has set up a campaign — called Buzz Off — that is calling for the Mosquito to be banned on grounds that it infringes the rights of young people. 'These devices are indiscriminate and target all children and young people, including babies, regardless of whether they are behaving or misbehaving,' Sir Al told the BBC. 'The use of measures such as these are simply demonizing children and young people, creating a dangerous and widening divide between the young and the old.'"
Two problems:
1: The tone is compressed with mp3. 25kHz isnt supposed to be even representable with that format. MP3 drops frequencies at 16kHz and above, right?
2: You cant properly represent a 25kHz tone with 44.1kHz sampling without distrotion. For all we know the real tone may sound like Mozart.
"What ever happened to just posting signs and asking people to leave and finally contacting the police if there was still a problem."
That's essentially the problem. I've been watching the coverage of this device in recent news with interest, and initially I was pretty furious that some politically correct hand-wringer was once again poking their nose in, but I must confess that there are always two sides to the story and I'm beginning to see that the device really does need some serious improvements and/or regulation or, ideally, the root problem being dealt with and the device being made unnecessary. And that's the real issue that this device is highlighting, to my mind - that there is a problem with the behaviour of certain groups of kids that we need to deal with.
A typical example is just down the road from my house. There's a small shop, video rental place, takeaway, and a pub in a small patch surrounded by houses. During the day, it's fine. At night, it's a disaster area.
The kids who gather there are an effing nuisance, they insist on playing football right in front of the cars trying to use the car park, they harrass people and treat adults there like crap, they've smashed the windows of the shops dozens of times, they throw rubbish everywhere... The list goes on and on, they're just out of control and their parents are nowhere to be seen. Nobody dares deal with it because if they do, *they* will be the ones who get punished for taking the law into their own hands, or they'll be on the receiving end of reprisals.
The police response is this: Several yellow signs have been put up on the lamp posts that have bizarre txt-speak drivel on them. A typical example is "If ur bad we'll tell ur olds."
And that's it.
You never, ever see the police turn up. They do *nothing*. The parents of the kids do *nothing*. For the reasons listed above, everyone else does *nothing*. The kids, meanwhile, go mental. It's a total failure of control.
