An optimal dimensioning method of a green wall structure for noise pollution reduction

Abstract : This paper concern the optimization of a multilayered green wall structure including substrate and foliage in order to reduce as much as possible backward noise reflection and forward transmission from the wall. Each component involved in the wall structure is fully characterized experimentally to get its transfer matrix. Simulation demonstrated that foliage layer superimposed to substrate layer doesn’t affect the transmission losses but contributes greatly to the increase of return losses of the green wall structure. To achieve the best perfor­mances in terms of return and forward losses as well as frequency bandwidth, the methods of optimization are discussed including selection of types of materials, thicknesses, arrangement of layers as parameters.
