FIELD: radio engineering.
SUBSTANCE: proposed vibroacoustic noise generator that can be used in information protection systems to produce noise signal for blocking voice information interception from locations designed for secret negotiations has microphone, microphone amplifier, log amplifier, splitter, n band filters, n scramblers, n random pulse generators, adder, power amplifier, and radiator. Effectiveness of noise signal produced by generator is independent of generator location, acoustic properties of room, vibration properties of guarding structures and engineering services, and type of radiators connected to generator.
EFFECT: enhanced efficiency of noise signal.
