The speech information protection system against leakage through technical channels “Sonata-AV” model 4B is designed to protect speech information in designated areas from leakage through acoustic, vibroacoustic and acoustoelectric channels.
The production of the Sonata-AV model 4B product is certified.
FSTEC of Russia Certificate No. 3625 dated September 20, 2016 certifies that the Sonata-AV model 4B Speech Information Protection System against Leakage via Technical Channels (hereinafter referred to as the Sonata-AV model 4B Product) is a technical means of protecting acoustic speech information processed in dedicated premises up to and including category 1, from leakage via acoustic and vibroacoustic channels and can be installed in dedicated premises up to and including category 1 without the use of additional information protection measures;
The first system-forming feature of the Sonata-AV model 4B Product is its design based on the principle of "single power source + generators-electroacoustic converters (emitters)" (see Fig. 1).
The main positive consequence of such a design is the potentially higher resistance to speech information protection due to statistical independence excitation of masking noise at all points.
In addition, such a design of the vibroacoustic information protection system (as opposed to the "classical" approach - "central generator + electroacoustic transducers"):
a) significantly simplifies the design and installation (it is possible to connect any combination of generators-emitters to one power supply loop);
b) allows for the implementation of a potentially lower interfering effect of the system at a given level of protection due to the possibility of individual adjustment of the integral level and correction of the spectrum of each generator-emitter.
The second innovative system-forming feature of the Sonata-AV Model 4B Product is the "intelligence" of its elements and the use of a wire line connecting the power source with others for information exchange.
The main positive consequence of such an innovation is:
a) the possibility of building an automatic control system for all elements of the Sonata-AV Model 4B Product at the lowest possible cost of equipment and installation;
b) reduction of labor costs for configuring and testing the system when installation and control as a consequence of the possibility of address control of the operating mode of each element of the system;
c) the possibility of changing the settings of the generators-emitters "on the fly" and, as a consequence - the possibility of building an adaptive ("multi-profile") vibroacoustic protection system that ensures compliance with the security requirements for various options for using the premises ("one in the office", "negotiations without sound amplification", "sound amplification equipment is on");
d) reducing the costs of creating a single TSZI complex, since a single communication and power supply line for the generators-emitters can simultaneously be used in the same capacity for other elements of the complex.
