Title: COMSOL modeling of geometrical impact of sonic crystal noise barrier attenuation
Keywords: Acoustic, COMSOL modeling, Noise barrier

Abstract: The present paper describes the impact of the change of different parameters of the geometry of the Sonic Crystals noise barriers on noise attenuation. Results with different peculiarities of the geometry are compared. Sound crystals, arranged in a different matrices were examined. The modeling is performed with the COMSOL program.
