In this paper we demonstrate the evaluation of spatial congruency of object based audio and 3D video reproduction. With current developments in 3D video representation we are able to introduce a depth dimension. Furthermore, audio reproduction systems like Wave Field Synthesis are able to reproduce the sound field of virtual sound sources at various positions in the room, also in front or behind a video screen. When combining these technologies audio objects can be placed at the positions of 3D video objects. Subjective evaluations are needed to investigate the quality of such combinations. In our experiment we displaced the audio and video objects with respect to certain angles and evaluated the noticeable horizontal displacement angle. Displacements of more than 5° are noticeable and become annoying above 10°.
