Introduction: The article is concerned with protection of acoustic information from leakage through the auxiliary technical tools and systems. This problem is often ignored in modern engineering. The author proposes the methods for preventing information leakage.
Materials and Methods: Special software and hardware system was used for studying the scope of the information leakage through acoustoelectric channel. This system has certification of information systems for compliance with information security requirements in the acoustic range. The researches were carried out in octave bands according to normative documentation of the control institutions (FSTEK, FSB).
Results: The research work was focused mainly on the measurement and evaluation of speech intelligibility due to interference of electro-acoustic components the auxiliary technical tools and systems. The results of the speech intelligibility measurement were received from many auxiliary technical means.
Discussion and Conclusions: The analysis of the research results allowed identifying the most vulnerable elements of the auxiliary technical tools and systems. The author proposes relevant measures for protection of acoustic information from leakage through acoustoelectric channel.

Keywords: MIC effect, magnetoacoustic channel, electroacoustic channel, speech intelligibility, technical channels of information leakage, formant method, octave band
