## Abstract

Room acoustic simulations performed with wave-based methods are becoming feasible alternatives to geometrical acoustics thanks to the increasing power of computers. In this preliminary study two of these methods are investigated: the Finite Difference in the Time Domain (FDTD) and the Equivalent Source Method (ESM). The Image Source Method (ISM) is also used as a reference for the comparison of results. The two methods chosen perform calculations in the time domain. This

has the advantage of obtaining results for all frequencies up to a selected limit at once instead of running a simulation for each individual frequency needed. Time-domain calculations also directly yield the impulse response of a room, from which can be derived the acoustic parameters and auralization signals.
