Identification Method of the Recording Position of Hyper-directional Microphones

Abstract (in Japanese) (See Japanese page) 
(in English) In order to realize the personal 3D sound field reproduction system using directional microphones and wave field synthesis, it is necessary to construct the microphone array using hyper-directional microphones. However, the shape of commercial hyper-directional microphones is cylindrical, it is difficult to identify the recording position by the observation of hyper-directional microphones. In this report, we propose the identification method of the recording position of hyper-directional microphones by using the measurement technique of an impulse response. The proposed method was applied to commercial hyper-directional microphones. As the result, the recording position of commercial hyper-directional microphones was identified.
