NATSONIC - Crowd Dispersal System

If you are fed up with anti-social behaviour from nuisance crowds then you an effective deterrent - NATSONIC Crowd Dispersal System.

NATSONIC is a new device specifically designed to disperse groups of youths from problem areas.

 

The system generates a pulsed, near ultra sonic tone at around 16KHz, close to the limit of the hearing range of people under the ages of 25.  The sound, whilst harmless, becomes highly irritating after approximately five minutes of exposure.  As a result people in the 20-25 age group leave the area, whilst the majority of people above this age are totally unaware of any noise. 

 

NATSONIC is ideal for:

 

  • Shop Entrances
  • School Grounds
  • Public Buildings
  • Petrol Stations
  • Car Parks
  • Railway Stations
  • Construction sites
  • Industrial Areas
  • Residential Areas
