Acoustic Noise Generator (2 Channel)
Own the top of the class noise generator. Do you suspect that you are being bugged?
Is there that sixth sense that something is happening and you need to know what
it is? Here is a powerful countermeasure device, the acounstic noise generator,
that renders bugs, or eavsdropping devices totally useless.
The ANG-2200 is designed to create a perimeter of noise around a target area
that defeats wired microphones inside walls, contact microphones, audio transmitters
located in AC outlets, and laser/microwave reflections from windows.
Most sound masking systems inject noise into an otherwise benign environment.
In this environment, the occupants must raise their voices above the noise level
to communicate, which invariably, eliminates the benefit of noise masking.
The masking system injects noise into the environment perimeter and not directly
into the environment. This approach allows normal conversation while defeating
eavesdropping devices that rely on acoustic leakage.

Eavesdropping Protection Against:

The acoustic noise generator is designed to create a perimeter of noise around
a target area where most sound masking systems inject noise into an otherwise
benign environment. In this environment, the occupants must raise their voices
above the noise level to communicate, which invariably, eliminates the benefit
of noise masking.
The ANG-2200 offers two channels each with a truely random noise source. Both
channels have a seperate high and low frequency control in order to compensate
for loses found in the enviroments material composition.
The noise masking system consist of a main unit (the ANG-2200) and three optional
accessories that are purchased to tailor the system to the environment of concern.
The ANG-2200 accessories are:
1. TRN-2000 Transducer used to inject acoustic noise into walls, ceilings,
windows, plumbing, and air ducts.
(ANG2200 can take
a total of 18 transducers. 9 transduers per channel).
2. OMS-2000 Omnidirectional Speaker used to project acoustic noise into
drop ceiling air spaces, closets, crawl spaces, and air ducts.
3. EAR-200 Electro-Acoustic Receiver used to evaluate the level of audio
leakage and set the specific masking level.
