Probably the largest pit-fall to accurate audio reproduction using wave field synthesis (WFS) is the listening space. The WFS theory assumes free field, source free conditions which are seldom the case for practical sound reproduction. There is consequently a need to determine what effect the reproduction room has upon the synthesised sound field. This paper presents a finite difference time-domain (FDTD) approach to predicting the sound field in a room with arbitrary geometry and frequency dependent absorbing boundaries. A significant benefit to using FDTD is that the WFS system can be modelled both as part of the room and also in free-field conditions therefore distortion of the sound field from the acoustics of the reproduction room can be quantified.
