“…When performing an active screen in the form of an electromechanical, for example, piezoceramic oscillating system, the processes of energy transformation and its formation in the surrounding spaces begin to operate in it. At the same time, in the process of energy conversion in the active screen, electric, mechanical, and acoustic fields interact [10,15,16]. The formation of acoustic energy is accompanied by the appearance of a multiple process of radiation and re-reflection of scattered sound waves, both by elements of the screen and by elements of the grid in which it is used.…”
