FIELD: the invention refers to electroacoustics and designed for generating acoustic vibrations of a sound frequency in aggressive medium at high pressure and may be used for example for diagnosing of high-forced combustion chambers.
SUBSTANCE: the mode is in that in gap between electrodes of high voltage working gas is fed , the arc is stroked and modulated. At that the modulation of the arc is carried out by influencing on it with alternate magnet field of a sound frequency.
EFFECT: increases intensity of vibrations at high temperature and pressure.
