This paper presents a noise evaluation system based on the finite element method using impulse response analysis and its auralization. The time-variant convolution is employed to treat the moving sources problem such as traffic noise. The PML boundary condition is employed to treat the open boundary condition. The system exposes the computed noise level to users with both the auditory information using sound source signal and the visual information using CG image. The computed results are compared with the measurement results in VR space.
