Purpose: design of the passive device of the speech information protection from acoustoelectric leakage channels and study of the characteristics of protection device using a virtual laboratory bench developed in the Matlab environment. Methods: mathematical modeling using Matlab environment. Practical relevance: designed in the Matlab modeling environment: an equivalent circuit of the telephone set, which makes it possible to simulate acoustoelectric information leakage channels, schematic diagrams of passive protection devices for telephone sets that implement protection methods: limiting low-amplitude signals, filtering high-frequency injection signals and disabling acoustoelectric transducers, a virtual laboratory stand for research of the characteristics of protective device. Using a virtual laboratory stand, the main characteristics of the developed protection devices were studied and their performance was assessed when connected to the telephone network.
