Design and Realization of a Reference Loudspeaker Panel for Wave Field Synthesis

Document Thumbnail

This paper describes the requirements, the design and the realization of a reference loudspeaker panel for Wave Field Synthesis (WFS). Beside the algorithm and the speaker's acoustical performance the quality of Wave Field Synthesis is strongly dependent on the spatial aliasing frequency. Only below that frequency will the synthesized wave field be physically correct. The spatial aliasing frequency is related to the distance of adjacent speakers in the loudspeaker array. To raise the aliasing frequency to 2.8kHz a loudspeaker panel was designed with a tweeter spacing of 6cm. The transducers, electronics and directivity were designed to obtain an excellent sound quality and SPL coverage. Simulations regarding the influence of speaker spacing and wave field artifacts have been made. Measurement results of the panel are given. The overall system design will be shown as an application example.
