How does the Mosquito™ system work?
Mosquito™ is essentially a sounder unit that emits a very high frequency modulated tone that is completely harmless even with long term use. The unit has been thoroughly tested by the NPL, NHS, ISVR, RSPCH, BSHC etc. to ensure it complies with all relevant legislation. Please find copies of these reports and more on the RESEARCH page.
I am not a teenager, will the Mosquito™ annoy me?
This is very unlikely and research has shown that the majority of people over the age of 25, have lost the ability to hear at this frequency range. It should be borne in mind, however, that the unit usually has the desired effect – moving the crowds away – within just a few minutes, at which time the unit can be turned off. So even if you are able to hear the noise to some degree, you would not have to put up with it for long.

gives you the chance to try to hear it at the teenage setting, and then gives an adult example of what a teen might hear.
Jeremy was so sad one night. He was at the computer and he said "Can you hear something?" I said "Yeah...kind of a high pitched irritating squeal". He couldn't hear it, his ears are too old!! Bahahaha. Well, next year maybe that frequency will be gone for me as well. At least I've gotten the chance to hear it once in my life :P
