What is TeenBuzz (or Mosquito Ringtone)
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.
