In this paper, a 3D audio system using multiple vertical panning (MVP), which matches audio to a large-screen multiview 3D video display system, is proposed. The vertical position of sound images is synthesized by the panning between two loudspeakers placed at the upper and lower sides of the screen. The horizontal position of the sound images is controlled by the position of two loudspeakers. Using the proposed system, multiple viewers can simultaneously feel the sound images at the position of 3D objects. A listening test was used to examine whether viewers can perceive the synthesized sound images at the position between two loudspeakers. The results of an audio-visual experiment show that the proposed 3D audio system was effective as compared with a conventional system because viewers could always feel the synthesized sound images at the position of the 3D video object.
