This paper is concerned with active control of generating a listening zone in a free space while producing a quiet zone in the same free space. In recent years, the reproduction sound of contents such as speech and music tend to increase in the space living by the spread of teleworks. A sound to the listener may appear as a noise to non-listener around the owner of sound player. Therefore, we propose the sound field control technology to convey the sound information only in the personal area at narrow space. Using three loudspeakers, the experimental result was confirmed by comparison with the simulation result.
