Modeling and simulation of the sound propagation by the FDTD method
Résumé
The FDTD (finite difference time domain) method has emerged as a promising technique for the study of the field sound propagation phenomena in room acoustics. Unlike the frequency modeling methods, this technique, based on the time and spatial discretization, can yield a temporal description of the acoustics waves propagation problem, which is useful in real-time simulation and auralization of room acoustics. In this paper, we discuss the implementation of a computer code based on the finite difference time domain method. We study and visualize the sound field propagation of an acoustic pulse in two-dimensional geometries rooms. The different results of the simulation will be compared to the an analytical solutions of the propagation wave equation in the same geometries.
