【 摘 要 】

In this article there is an analysis of using noise-absorbing screens on the basis Helmholtz resonator to reduce the level of acoustic noise on open industrial sites of machinebuilding plants and adjacent living areas. A design realization of this screen was considered, the characteristic of which is a variable depth of the resonator chamber and the change of the clearance of the resonator throat. The evaluation of the efficiency of using the screen was performed using experimental modeling with an acoustic chamber and a screen model. It was shown that in the majority of the cases there is some attenuation of the acoustic signal in the zone in front of the screen. A conclusion was made about the possibility of reducing noise level in industrial and living zone
