PROBLEM TO BE SOLVED: To improve the accuracy of impulse response. An acoustic wave propagation simulation system 1 includes an input device 2, a ray trajectory calculation device 4, a ray trajectory recording device 5, a ray intensity and arrival time calculation device 6, and a ray intensity and arrival time correction device. 8, an impulse response calculation device 10, and an impulse response recording device 11. Obtaining multiple ray trajectories that reach the receiving position from the sound source position and using the boundary conditions set at the boundaries of the sound field The calculation result C of the amplitude is obtained. For a ray locus having a reflection position in a designated area provided at the boundary of the sound field, a correction result F is obtained by correcting the arrival time and the amplitude using the partial boundary condition of the designated area. Based on the arrival time and the calculation result C of the amplitude, the calculation device 10 preferentially uses the correction result F when there is the correction result F to obtain the impulse response I at the reception position.
