This paper presents a noise evaluation system based on acoustic wave theory. This paper utilizes two methods – the finite element method and the boundary element method using a fast multipole method, and compares the numerical results of the benchmark problem. In addition, we show the results using the analytical model of the complex shape based on standard specifications of noise barriers and discuss the difference of the numerical results and auralization results between the two methods.
