Abstract

With sonic crystals it is, analog to photonic crystals, possible to produce band gaps. These acoustic band gaps are the reason why sonic crystals are almost opaque for a certain frequency range, while not influencing other parts of the acoustic spectrum. These properties make sonic crystals very interesting for noise protection. The main focus of this paper stands on the open source simulation methods, which were used to investigate the properties of sonic crystals. Therefore two-dimensional simulations were performed to get angular dependent transmission coefficients and sound attenuations for a test noise barrier. The two mainly used open source computer simulation tools were Elmer and openBEM. Elmer is a complete FEM multiphysics suite and openBEM is a boundary element solver specifically designed for the Helmholtz equation. Keywords: sonic crystals, simulation, open source
