Abstract (in Japanese) (See Japanese page) 
(in English) It is very important to develop near 3D sound field reproduction techniques in order to realize the ultra-realistic communications such as 3D television and 3D tele-conference. In this report, the near 3D sound field reproduction system using directional loudspeakers and wave field synthesis was developed by constructing the surrounding microphone array and the radiated loudspeaker array. In order to evaluate the performance of the developed system, the estimation of sound image positions synthesized by the radiated loudspeaker array was performed by the sound source search system. As a result, it was indicated that the sound images were estimated at the desired positions.
