The Mosquito or Mosquito alarm is an electronic device, used for solving loitering problems, which emits a sound with a high frequency that can generally be heard only by young people. We have turned it into a ringtone that can't be heard by old people!
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.
