Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes an improved method for a localized sound field reproduction system.
The method realizes a system which adapts to fluctuations of acoustical environments to avoid deterioration of the localization performance in such changing condition caused by conventional methods.
The proposed method can also realize flat and accurate reproduction of sound in the localized field in addition to large damping in the outside field, by introducing combination of original reproduction control units.
Feasibility of the method is confirmed by computer simulation.
