The DNG-2300-8 3-Channel White Noise Generator with 8 Transducers was created to keep conversations and information private. Conduct confidential meetings and speak freely in your office, conference room or any private space. Listening devices, bugs, thin walls or the carrying of a voice don’t stand a chance against the DNG-2300-4


3-Channel White Noise Generator with 8 Transducers


How does it work?
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.


How many do I need?
You’ll want to have a good spread of transducers and speakers amongst the wall space, the number will depend on the size and construction of the room. This package comes with [1] DNG-2300, [8] TD-2300 and [1] SP-2300. See example below.
