High Frequency App Sends Ringtones Only Teens Can Hear
Beep is courting only the youngest demographic, with ringtones that only they can detect
In what could be the most frustratingly ingenious application of teenage subterfuge to date, the Beep app was built to let youth communicate without their parents or teachers noticing.
The application sets a smart phone to send notices — such as those for an incoming call or text message — at a frequency of 14,800 hz. As people age, the upper range of their hearing diminishes. The frequency Beep uses falls in a range that most teens can still hear, but most adults cannot. Where a specific individual loses the ability to hear sounds in Beep's range varies from individual to individual, but in general people old enough to drink aren't old enough to hear it.
