Fanta Stealth Sounds by Ogilvy & XS2TheWorld

Fanta believe teens should have the right to play. The brief was to produce a mobile phone application for teenagers so they can play without their fun being stopped by adults.

The idea was inspired by the ulta-sonic alarms used to stop teenage groups gathering - these play high-pitch sounds which only young people can hear. When you get older you can't hear these sounds as your hearing naturally gets worse.

The Fanta Stealth Sound System, allows the same teenagers to communicate between themselves using frequencies adults cannot hear. We used simple, graphic icons to give the application truly global reach.
To date the application has had over 400,000 downloads since it's UK launch.
It was launched worldwide in July 2009
