PROBLEM TO BE SOLVED: To facilitate the positioning of a microphone, hold the microphone in a stabilized state, and suppress the turbulence of a sound field to the minimum. SOLUTION: Through-holes 8 arranged uniformly longitudinally and laterally are formed in a mount plate 4 on which a microphone 2 is mounted. Each through-hole 8 is configured into a square shape having one side substantially equal to the diameter of the microphone, to the interior of which there is stuck a rubber member for holding the microphone resiliently. The microphones of a predetermined number are inserted into the through-holes 8 positioned at sound pressure measurement points and are positioned to form a microphone array. COPYRIGHT: (C)2004,JPO
