Realistic sound reproduction using Wave Field Synthesis in concert halls involves ensuring that both the direct and reverberated sound fields are accurate at all listening positions. Though methods for controlling the direct sound field have been described in the past, the control of the reverberated sound field associated to WFS sources remains a topic of interest. This article describes the characterization of the reverberated sound field associated to a WFS array as it synthesizes a virtual point source. Variations in the directivity and positioning of the virtual source are shown to have an effect on the associated room effect. A solution for controlling the reverberated sound field in a concert hall equipped with a WFS system is proposed, based on this characterization.
