Here is an interesting story of the day. Basically a company in the UK discovered that certain high-pitched frequencies can not be heard by people that are over 40 – but they can be detected by teens. They used this knowledge to create a product that will emit the frequency in order to deter teens from hanging out in front of their stores or other such activities.
The name of this product? Chavbuster.
So you might be asking yourself – what is a Chav?
From wikipedia: Chav (pronunciation: [tʃæv]) (also Chavette (female chav), Charv or Charva) is a slang term in wide use throughout the United Kingdom since 2004. It refers to a subcultural stereotype of a person with fashions such as flashy “bling” jewellery, Burberry clothing items and counterfeit designer clothing; an uneducated and uncultured background; a tendency to congregate around places such as fast-food outlets, bus stops, or other shopping areas; and a culture of antisocial behaviour and violence. Chavs often listen to dance/trance, RnB, rap, hip hop and drum and bass music . Response to the term has ranged from amusement to criticism that it is a new manifestation of classism.
The best part about this article is the fact that teenagers have actually used this technology and turned it into something useful for themselves. They have taken the frequency and made it into a ringtone for themselves. This means that they can turn their mobile phones on in class and have them ring – without the teacher hearing it. Awesome!
