METHOD OF RECONSTRUCTING MULTI-PARAMETER MODELS OF OSCILLATORY PROCESSES OF MECHANICAL SYSTEMS Russian patent published in 2014 - IPC G01M7/02 G06T17/00 

FIELD: physics, acoustics.

SUBSTANCE: invention relates to acoustics and is intended to generate acoustic waves in a gaseous medium. A method of generating the acoustic waves is carried out by forming an oscillatory body from a cloud of ionised gas in an electrostatic field with subsequent simulation of the oscillatory body with a high-frequency electric field, wherein the electrostatic field used is an alternating electric field. The apparatus for implementing the method comprises two acoustically transparent electrodes 1, divided by a dielectric housing 2, having a cavity 3, which forms with the electrodes 1 an ionising chamber, an ionising electrode 4, a dc voltage source 5 and a voltage modulator 6.

EFFECT: invention enables to generate acoustic waves in a wide frequency and power range.
