A scheme is proposed, in which the locations of the noise sources, special housings with ferroelectric ceramics coating that through direct and inverse piezoelectric record an acoustic signal with built-in microprocessor analyzes it and generates a response in anti-acoustic wave. As the technology of coatings applied ferroelectric ceramics gas-dynamic spraying. In this paper the dependence of the acoustic power of the change in the area of the electrode surface and the polarization voltage. To increase the effectiveness of noise reduction of working arrangements, where their amplitude – frequency characteristics are very different from each other, including the width of the preferred frequencies proposed multicell design ferroelectric ceramics layer.
Keywords: piezoelectric effect, acoustic power, frequency response, resonance frequency.
