PROBLEM TO BE SOLVED: To provide a noise measuring system manufactured at a low cost, excellent in workability in the manufacturing and maintenance, and capable of setting a relative position between a microphone and a measured object by simple structure. SOLUTION: In this noise measuring system of the present invention, the relative position of the microphone 10 to the measured object 50 mounted on a rotary table 21 is set freely on a hemispherical face, by rotation of the rotary table 21 due to a rotary mechanism 41, and by rotation on a semicircular arc of an arm 3 due to a rotary mechanism 42. That is, a positional relation of the one microphone 10 to the measured object 50 is set freely by the simple structure comprising only the two rotary mechanisms. COPYRIGHT: (C)2005,JPO&NCIPI
