Title: An investigation of the influence of the geometrical parameters of a passive traffic noise barrier upon the noise reduction response
Keywords: Acoustic barrier, noise reduction, COMSOL model

Abstract: The influence of the construction barrier thickness and profile radius upon the noise reduction in a new passive traffic noise barrier is investigated in this study. Numerical model and simulation is used after verification of the numerical procedure results using experimental setup results. Some useful conclusions about the barrier geometrical parameters design are found.
