We are studying 3-D sound image reproduction systems associated with 3-D video images with the goal of creating a highly realistic form of 3-D TV broadcasting in the future. This paper describes a method of 3-D sound image control using loudspeaker arrays that can control the position of the sound image arbitrarily and continuously. Two kinds of subjective listening test were conducted for distant and directional perception. We confirmed that the position of the sound image can be controlled in 3-D space by using this method.
