WNG 023 Acoustic Noise
Generator
The WNG 023 Acoustic Noise Generator is intended
for the protection of negotiations from overhearing aided with special
technical means (STM).
Its main function is the generation of the so-called 'white noise'
in the acoustic range of frequencies, which ensures a drastic reduction
of speech comprehensiveness (up to a complete incomprehensibility)
upon recording and retransmission by various types of STM's.
WNG 023 can serve as a stationary unit (powered by the power unit
supplied with the delivery set), and as a portable one, powered by
an accumulator battery, if field operation is required - e.g. in an
automobile.
WNG is an effective security tool within confined spaces. Maximum
space protected is 40m3.
It should be noted, that as the white noise is generated in the frequency
range of the human speech, its use involves a certain degree of discomfort
for the negotiators.
