Ringtone that your parents/teachers cant hear.

Teen Buzz (also known as Mosquitotone or Zumbitone) is a popular ringtone that was hijacked from a technology that was originally used to repel loitering teenagers from shops in the United Kingdom. Inventor Howard Stapleton developed the "Mosquito device" for Compound Security Systems.

This device emits a modulated 17 kHz sound that proves to be a great annoyance to teenagers or anyone younger, but leaves most over thirty years of age unaffected. This is due to presbycusis, a normal loss of acute hearing that occurs with advancing age.

TeenBuzz mosquito ringtone was developed using the same technology, but as a constant 17 kHz high frequency ringtone. It is primarily used in the classroom, allowing students to be alerted of incoming text messages on their mobile phones without the knowledge of their teachers.

The company that developed the device said that they were impressed and admits to the idea being humorous, although they considered it may be an infringement on their intellectual property rights. They developed their own ringtone which they sold as the authentic mosquito tone.

The short version, A tone outside the audible range of hearing for most people over the age of 30. This means that you can get phone calls and receive text messages in class or school without teachers hearing it.

I have tried it and my parents didnt hear a thing. I have included in the zip files ringtones of different frequencies. Try each of them .

For instance, if you can hear the 17khz and the 18khz tone, use the 18khz - less people will be able to hear it.
