Abstract
Simulation of sound wave propagation is widely used thanks to advances in the computing environment and the spread of simple simulation algorithms such as the finite difference-time domain (FDTD) method. In this paper, the theoretical basis for the analysis of sound wave propagation is described, after which discretization using the FDTD method and the boundary conditions are described. The compact explicit-FDTD (CE-FDTD) method, which is a highly accurate version of the FDTD method, is also described. For application of simulation of sound wave propagation to auralization, sound field rendering, which is a technique for 3-D auralization on the basis of computerized 3-D numerical models, is also described.
