[Poster Presentation] Improving spatial sensitivity characteristics of an arched vertical microphone array

Abstract (in Japanese) (See Japanese page) 
(in English) For clear recordings of distant speech, it seems effective to produce a local zone around the signal, wherein the spatial sensitivity for the speech is enhanced. To this end, we have been studying a way to produce such a zone in the horizontal plane by using an arched vertical microphone array. In this report, in order to improve the spatial sensitivity characteristics, we first modified the arrangement of the sensitivity-control points for the microphone array. In addition, we adopted the following two methods:
(1) using null-point of a directional microphone.
(2) dividing the microphone array into two arrays lining up back and forth, or left and right.
