Reproduction of Arbitrarily Shaped Sound Sources with Wave Field Synthesis - Discretisation and Diffraction Effects

Current Wave Field Synthesis (WFS) implementations only allow for point sources and plane waves. In order to reproduce arbitrarily shaped sound sources withWFS several aspects need to be considered, such as the WFS-operator for source points outside of the horizontal plane, discretisation of the object surface and diffraction of the sound around the sounding object itself, which can be modelled by introducing secondary sources at the edges of the object. This paper discusses those issues, describes the implementation in software and shows results of both objective and subjective evaluation.
