Abstract The paper covers researching and optimization of acoustic tract of monitoring system SAC-02.000 intended for ecological safety increasing. For increasing signal-to-noise ratio of the SAC-02.000 the analysis of the acoustic tract was held, the ways of optimization of near- and far-fields of reception path were brought forward.
