Ultrasonics are great new ringtones that play at a higher frequency than normal tones. This means that they can only be heard by kids and generally can't be heard by adults over the age over 20 or so.
What are these Free Mosquito Ringtones all about?
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.
