In this study, we examine the acoustic simulation method combining the wave equation finite difference time domain (WE FD-TD) method and compact FDs (CPFDs) for the second derivative. The wave equation compact finite difference time domain (WE CPFD-TD) method does not require calculation of the particle velocity; therefore, it can reduce the calculation time and memory used. Furthermore, for acceleration of simulation, we employ the recursive filtering algorithm and graphics processing unit (GPU) computing. As a result, we clarified that the three-dimensional WE CPFD-TD acoustic simulation using GPU is ca. 25--30 times faster than that using CPU with OpenMP.
