I recently came to know of this fascinating idea “Teen Buzz”
Teen Buzz is a ring tone optimized at 17.4 kHz which can only be heard by people less than 25 years of age because the ability to hear high frequencies deteriorates in humans with age. It is quite popular among teens in the United Kingdom who use it in schools so as to prevent disciplinary actions that would normally be imposed if a mobile phone user was caught using their phones during school hours.
You can hear the tone here

though, i’d like to tell u, it’s not just used in UK.. 😛
