Research of the Acoustoelectric Speech Information Leakage Channel Based on Acoustic Transducers

摘要

There is a huge amount of equipment that is installed in rooms and has the function of play or record sound. Such devices usually contain speakers and microphones, which are acoustic transducers. The use of such transducers leads to the appearance of acoustoelectric speech information leakage channels. In this paper, typical acoustic transducers are explored: electrodynamic, electromagnetic, piezoelectric. Their main characteristics were investigated when used in the sensor mode. The results obtained can be used in the educational process in the study of acoustoelectric channels of information leakage. These studies are fundamental for the design of virtual acoustoelectric transducers in a simulation environment.
