Abstract (in Japanese) (See Japanese page) 
(in English) Recently, the binaural the technology which it reappears faithfully at binaural position of the receiving person has been researched the sound signaling which is recorded. With this examination, the inversed filter is produced, this is actualized by the fact that the speaker is used. With this examination first, you express in the change of acoustic property between the speaker \& the both ears concerning the producing algorithm of the following possible inversed filter. Next, the fact that the receiving person can produce the sound field space freely by the fact that the inversed filter and the optional zone control filter are combined is shown. Furthermore, effectiveness of this proposition is verified by computer simulation. Lastly, the effectiveness for actual environment by the fact that simulation is done making use of the impulse response of the actual room space, is verified.
