You might have heard of (or heard if you’re young enough)the Mosquito Teen Repellent, a sound box put where youngsters hangout which plays a sound at a frequency only they can hear, in order to send them on their way.
Fanta have decided to help youngsters make use of their ability to hear frequencies not heard by those over 20. They have created a mobile phone application that can play a series of tones that represent various messages, and can be used as ring and message tones. Am sure kids can use this idea to create chaos throughout classrooms across the country.
A really good example of giving the audience something useful (in a annoying a teacher kind of way) that they feel is targeted specifically at them.
