Abstract

Sound field simulation is widely used because of the progress in computer environments and the spread of simple and easy simulation algorithms such as the finite-difference time domain (FDTD) method. In this paper, the theoretical basis of the FDTD method for sound field analysis is first described, then the implementation of the FDTD algorithm on a graphics processing unit is described. For the application of sound field simulation to auralization, sound field rendering is described. Sound field rendering is a technique for auralization from three-dimensional numerical models constructed by a computer, with a similar concept to the graphics rendering technique. An example of sound field rendering in collaboration with a head-mounted display is described.
