Sonic crystal for sound
WebThese crystals are made of periodic distributions of scatterers embedded in a matrix. Under certain conditions, acoustic band gaps can form. These are spectral bands where … WebFigure 3 Configuration used in a FEM model representing the periodic sonic crystal noise barrier with rigid scatterers. To evaluate the IL of the sonic crystal noise barrier, two lines of receivers (positioned at 1.2 and 1.4 m from the line source) are used. The result obtained by the FEM is used to verify the result of the infinite
