This study aims to examine the acoustic behavior of sound barriers categorized as sonic crystals. As part of the research project, we will assess the effectiveness of arrays of acoustic elements in mitigating noise produced by acoustic sources. More specifically, we will calculate the reduction in acoustic pressure at various frequencies resulting from the placement of sound crystals (calculation of the reduction index of sound barriers - insertion loss). These calculations will be conducted using the finite element method at a theoretical level. In this thesis, we looked into different ways of arranging arrays to create specific band gaps.
