Abstract (in Japanese) (See Japanese page) 
(in English) We suggest two microphone that can make up the dead angle in the direction of the noise in the context of the voice and noise arrive at the same time.
In the proposed system, we check that can make up the dead angle in high reverberation by using the proposed system by configuring the system that the adaptive filter work only in the derection of causality is satisfied and
using cascade connection recursive and non-recursivefilters as adaptive filter.
Keyword (in Japanese) (See Japanese page) 
(in English) high reverberation / law of causality / dead angle / adaptive filter / equation error method / cascade connection of recursive and non-recursive filters / lattice filter /
