Abstract

An experimental study investigated the performance of an innovative Wave Field Synthesis (WFS) system in terms of a listener’s ability to localize sound sources in the median plane. Performance was measured by localization accuracy, precision and response time under a variety of conditions that included two seating positions, five levels of elevations, and two spatial precision settings. Localization precision was 6°– 9° with only 24 loudspeakers in the WFS system covering the frontal quarter of the upper half sphere of the listening space. Localization performance was good in comparison to other studies with denser loudspeaker arrays or with other reproduction techniques. The implemented 3-D WFS technique is a serious alternative to other state-of-the-art spatialization methods.
