The unit protects a room by using the induction noise is not filtrable in the surfaces. This noise, also known as 'white Noise' , is transmitted by the surfaces with the help of a few transducers and the built-in speakers of the unit. The number of transducers and speakers is dependent on the configuration of the room.
Thanks to transducers the protection level of the generator is far better than the systems that only have speakers.
The transducers pass the greater part of the noise generated in the form of vibration, which allows you to produce interference less audible. Despite the fact that a slight noise can be heard in the interior of the protected area, there will be no need to force your voice.
This device protects you from:
- Surveillance systems, Laser and Microwave that use the reflections of the windows
- Electronic stethoscopes (contact mics)
- Built-in microphones on the walls or other constructions
- Other forms vibro - acoustic filtering of information
HOW IT WORKS
The acoustic vibrations are possible due to the ability of the sound waves expand through the walls, windows and other constructions. In some materials, the sound spreads even better than in the air. For example, the water is a great conductor of sound and the heating system can easily be used to access and steal the conversation.
It is the same principle used by the electronic stethoscopes. These pick up the vibrations caused by the conversations on the walls, windows and other constructions and transform them back into sound. These teams listening can be installed not only in the adjacent rooms, but even through a large number of floors or rooms.
Main reasons of the protection
The White Noise can block and disable these methods of listening. This is done with the help of the transducers special. Its parameters are optimal for many types of surfaces. The White Noise has a good performance which means that only a negligible part of noise occurs in the environment, while a large amount of vibration injected into the structure of the stay in the form of vibration, making it impenetrable to all this kind of methods of listening, even analog systems. With the help of the support of the transducers can be mounted in virtually all kinds of surfaces.
The speakers omni-directional masking may also be used with this device. Their purpose is to produce noise, non-filtrable spaces such as ducts of vents, under ceiling tiles, etc
Note: for the operation of this equipment are required of speakers, omni-directional transducers and for doors and windows that are available in the accessories section.
