Wave-field synthesis aims at creating a predefined sound field within a restricted listening area. Implementing and maintaining a wave-field-synthesis system is rather costly, as a high number of loudspeakers must be set up meticulously and driven individually. Despite this effort, a physically perfect synthesis is not possible. This contribution addresses a critical and relevant benchmark of synthesis quality: perceptual directional resolution. The study was conducted with a typical living-room-scale system by measuring minimum-audible angles in the horizontal plane with different stimuli. The results indicate that the procedure provides a directional resolution close to that of real sound sources.
