| Abstract(in English) | NHK has been developing a portable single-unit microphone for the simultaneous recording of 22.2 multichannel audio. Since each channel of the multichannel audio corresponds to a direction of sound, each output of the multichannel microphone should have narrow angle directivity corresponding to the direction of each channel. This paper reports the comparison results of three methods for achieving narrow angle directivity, which are spherical microphone with acoustic baffles that partition the sphere into angular segments, line array microphone having leaky acoustic tube, and spherical microphone which have microphone elements on rigid sphere. The simulation shows that line array or sphere with acoustic baffles are proper for narrow angle directivity. |
