The DNG2300-4 white noise generator is great for small areas to help to keep conversations and information private. Have confidential meetings and speak freely in your office, conference room, labs or any private space.

It is well-known that sound permeates through walls, doors, water, windows and other constructions as well as through voids, cavities and ventilation shafts. These outlets makes it possible
to intercept conversations conducted within a room or any premises with the help of highly sensitive contact microphones (electronic stethoscopes), window laser systems or conventional microphones without entering the room ( target area). All kits are made to order.

Listening devices, bugs, thin walls or the carrying of a voice don’t stand a chance against the DNG2300-4 White noise generator sound masking system.
When the white noise generator is paired with the transducers and speakers, it produces a low level audible interference by creating vibrations onto the surface of the walls in the protected space. If any form of eavesdropping devices are used it will block the voices and instead it will pick up and relay back the vibrational white noise created by the counter surveillance device. You’ll want to have a good spread of transducers and speakers amongst the wallspace, the number will depend on the size and construction of the room. (all devices also sold separately) installation required.

The 3 Channel White Noise Generator helps protect from

• Laser & Microwave surveillance systems using reflections from windows
• Electronic stethoscopes (contact microphones)
• Microphones built in the walls or other construction
• Other Vibro-Acoustic methods of information leakage
