Abstract: Conventional audio systems use psychoacoustic knowledge to create a sound which is perceived equivalent to natural auditory events. Wave field synthesis (WFS) has overcome several disadvantages of conventional stereophonic audio systems by physically synthesizing natural wave fields. A practical implementation of a wave field synthesis system leads to errors which the literature proposes to compensate by physical means (e.g. compensation of shadow waves via compensation sources, modeling reflections from the third dimension via 21⁄2D-operator) or by a combination of WFS with conventional stereophonic sound (e.g. compensating aliasing errors by optimized phantom source imaging (OPSI)). This paper introduces a psychoacoustic approach to compensate synthesis errors to ensure a proper localization, sound coloration and spaciousness. Incitements for further psychoacoustic WFS research topics are given.
