In a previous article, we wrote about a ring tone that only teenagers can hear. They use it to fool adults into thinking that they aren’t using a cell phone, such as in school where cell phones may be banned. Now, it seems, the adults are getting back at the teens, taking advantage of the sound to repel teens from hanging out in places where they are not wanted, such as in front of an apartment building, at the street corner or on school grounds after hours. But the device is highly controversial. Human rights activists and civil liberties unions say that it is a weapon impinges on the teen’s rights and that putting such a crowd control device into the hands of the public is dangerous.
The device, called the Mosquito and sold under the company name “Kids Be Gone,” works by emitting a high frequency sound that has been compared to the sound of nails run across a blackboard or a mosquito buzzing around your ear. Usually, only people in their teens and twenties can hear the sound, because they still retain the sensitive hairs in the ears that are later damaged or missing in adults. How much your hearing has deteriorated over the years or has been damaged by loud noises will determine whether or not you can hear the noise. Another interesting aspect of this sound is that babies and animals can hear it, although it doesn’t seem to bother them the way it does bother teens and young people. Anyone over 12 that can hear the sound can only tolerate it for a few moments and say that it “drives you crazy.”
About 1,000 of the devices have been sold in the United States and Canada, and it is also being sold in England, Scotland and Australia. Owners use the device to repel youth from hanging around the area, and have high praises for the effectiveness of reducing youth-related crime.
What do you think of the Mosquito device? Is it a good idea or bad idea?
