MICROPHONE AND MICROPHONE ARRAY

摘要

PROBLEM TO BE SOLVED: To provide a simple and compact microphone array capable of accurately measuring the sound pressure distribution of sound sources distributed in three-dimensional space. SOLUTION: The microphone array 2 for detecting sound emitted from the sound sources distributed in the three-dimensional space is provided with both a plurality of microphones 20 in which sensor parts for detecting sound pressure from an object to be measured 8 having the sound sources are arranged in the approximately same direction and a frame 30 for arranging the plurality of microphones 20 along a plane or a curved surface. The plurality of microphones 20 are each provided with a position adjusting means for adjusting the distances between the sound sources and the sensor parts. COPYRIGHT: (C)2005,JPO&NCIPI
