SEL SP–157 - acoustic and vibroacoustic protection system of speech information

System is a technical mean of information protection, intended for protection of premises from soliciting through walling and engineered techincal communications. Operating principle is based on forming wideband acoustic and vibroacoustic masking noise interferences (analogue white noise or mixed with a digital speech-like interference). The system consists of a central generator unit and connected to it by wire passive electromagnetic (vibration) or electrodynamic (acoustic) transducers.
