Sound Source Localization by 3-D Sound Intensity Measurementusing a 6-channel microphone system　Part 2: Application in room acoustics

摘要

In room acoustics, a lot of information would be obtained if the directions of the directsound and early reflections could be determined. For this aim, the applicability of the 6-channel microphone technique using six cardioid-type uni-directional microphones wasexamined. With this measurement technique, the instantaneous sound intensity in a 3-dimensional space can be detected. In this study, the applicability of this method to roomacoustic measurements was investigated by performing basic experiments to analyze thedirect sound and discrete early reflections. As another application of this technique, soundsource localization in a room was investigated.
