Analysis of the acoustic channel of voice information leakage in a protected room

Abstract

Protection of speech information in a dedicated room begins with the assessment of acoustic and vibration channels of speech information leakage [1, 2]. The research methodology based on creating acoustic signals in a dedicated room and then measuring the level of acoustic signals outside the room is rather complicated and time-consuming. Therefore, to assess the channels of speech information leakage, it is possible to use the results of the analysis of the acoustic channel of information leakage based on the physical model of the propagation of speech signals in the form of acoustic waves outside the allocated room.
