Title: Models in COMSOL of Attenuation of Sonic Crystal Noise Barrier depend on Different Form
Keywords: Attenuation , COMSOL , Models , Sonic Crystal Barrier

Abstract: In the present publication we have designed models in COMSOL of noise barriers. The influence of the attenuation of the different geometric shapes of the barriers at different frequencies is considered and analysed. The influence of shape at different frequencies is very important parameter and can be decisive. Depending on the application, based on the performed analyses and the obtained results, the most suitable noise barrier, depending on the application, can be selected.
