Technology at work: Teenager Repellent

When I come across an interesting use of technology, whether related to business intelligence or not, I like to bring it to you here. This shop owner invented a device that apparently emits an irritating high pitch that he cannot hear himself (he used his daughter to test it) but is designed to rid the teenage hangouts from loitering about his place of business. Since we lose ranges of hearing as we age, only the younger set (under 30 is mentioned) should hear it and be repelled by it.

Teenagers, however, have taken the technology over to their advantage by using it for ring tones in classrooms where teachers cannot hear it.

Ahh, technology. I'll call that even. Read about it here.

I tested it with my 9-yr. old son and, while I can still hear it, I cannot hear it as well as he can. Listen here (to the tone or to silence depending on your hearing.) ;-)
