Abstract: It was established experimentally that during SHS, reaction systems (Ni–Al, Ti–B, Mo–B, etc.) generated acoustic oscilations in the frequency range from 5 Hz to 1.1 MHz with a pulse power of up to 17 W. It was found that the combustion of different systems is characterized by an individual set of dynamic parameters of acoustic emission in the modes of low ordered discrete pulses and highly ordered self-oscillations. It is shown that the spatial zone of acoustic emission is localized near the combustion wave. Analysis of the acoustic emission mechanisms of SHS is performed.

Keywords: combustion, heterogeneous system, acoustic emission.
