In this chapter, analysis of sound and vibration using the Finite-Difference Time-Domain method (FDTD method) is illustrated. In Sect. 2.1, the fundamentals of the FDTDmethod are described. In the FDTDmethod, several error factors caused by discretization of sound field are pointed out. As methods to solve such problems, in Sect. 2.2, the compact finite difference is described in detail. The FDTD method can not only be applied to acoustic problem of air-borne sound, but also vibroacoustic problems such as a floor impact sound and a sound insulation problem through a wall structure. In Sect. 2.3, therefore, application of the FDTD method to vibroacoustic problems is focused on, and the theoretical background and its numerical formulation are described in detail.
