ACOUSTIC NOISE GENERATOR
Produces An Audio Blanket That Defeats Eavesdropping
In Ceilings, Walls, Window Viberations, AC Ducts,
Plumbing And Other Places TSCM Sweeps Can Miss
The ANG-2000 is designed to defeat 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.
REI's 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.
Features
The REI noise masking system consist of a main
unit (the ANG-2000) and three optional accessories
that are purchased to tailor the system to the
environment of concern. The ANG-2000 accessories
are:
TRN-2000 Transducer used to inject acoustic
noise into walls, ceilings, windows, plumbing,
and air ducts.
OMS-2000 Omnidirectional Speaker used to project
acoustic noise into drop ceiling air spaces,
closets, crawl spaces, and air ducts.
EAR-200 Electro-Acoustic Receiver used to evaluate
the level of audio leakage and set the specific
masking level.
