摘要

This paper illustrates the visualization method of transient sound propagation in 3-dimensional semi-closed sound field in which a rectangular shape of room is modeled by applying the finite-difference time-domain (FDTD) method. As a direct time-domain simulation the technique of FDTD owns unique advantage in solving acoustic problems in closed and semi-closed rooms. To ensure the accuracy of the FDTD, some attention is paid in this paper on the key problems such as: numerical stability, numerical error, boundary condition, and the excitation signal. This paper uses slicing to visualize the 3-dimensional semi-closed sound field, and that validity is proved by the visualization of a 2-dimensional semi-closed sound field.
