Fanta’s new [mobile app](https://www.trendhunter.com/trends/screenable-app), Stealth Sound System, uses a surefire way to target a specific market. The app is meant as a way for teens to communicate on their cell phones without adults hearing them, and the Stealth Sound System features high-pitched sound frequencies that are inaudible to most people over 20.

Fanta’s Stealth Sound System is based on a controversial technology known colloquially as [Mosquito Teen Repellent](http://www.compoundsecurity.co.uk/), which was developed by Howard Stapleton a few years ago to deter teens from loitering outside London shops.

Within Stealth Sound System, individual frequencies are tagged to represent phrases, essentially creating a [new language only teens can hear](https://www.trendhunter.com/trends/duolingo-ads) and understand. Stealth Sound System was developed by [Ogilvy Advertising](https://www.trendhunter.com/trends/hiders-keepers).
