The DNG 2300 3-channel white noise generator protects against listening devices that can not be discovered by the usual counter-surveillance methods.
We know that sound has the ability to pass through walls and windows, as well as materials that do not pop to mind immediately, like water. It also passes through ventilation shafts, cavities, and voids. That makes it possible to listen to conversations that are taking place in closed rooms, with highly sensitive microphones, laser systems, or even conventional microphones.
The DNG-2300 white noise generator and its transducers and speakers, create in a way, a sound curtain around the space using a white noise that can not be filtered. In that way, the sound (a confidential conversation for example) can not leave the room, and thus can not be eavesdropped upon with a stethoscope or laser microphone.
DNG 2300 protects from:
- Laser and microwave surveillance systems using reflections from windows
- Electronic stethoscopes (contact microphones)
- Microphones built into the walls or other constructions
- Other vibro-acoustic methods of information leakage

By surrounding the structures and cavities with a non-filterable noise it creates powerful protection against all types of vibroacoustic surveillance, and the leakage can not take place.
In other words, by creating the white noise, and evenly distributing it through the spectrum of the human voice, while simultaneously using the wire-connected transducers
, it suppresses all available methods of vibroacoustic leakage.
Each of the Transducer
channels can feed up to 12 transducers mounted on solid structures like concrete, cement, and bricks. It can also feed up to 24 transducers on light structures like glass, pipes, drywall, or wood. The speaker's channel allows up to 12 speakers
, and the mute control input allows the user to turn Off the speakers temporarily.
