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 communication such as 3D television and 3D tele-conference. In this report, in order to evaluate the performance of sound image localization in the developed near 3D sound field reproduction system using directional loudspeakers and wave field synthesis, the positions of sound images were estimated by two methods (computer simulation and acoustical measurement) and the estimated results were compared between two methods.
