(Means for Solving the Problems) The present invention was made to solve these problems and to expand the measurement function in three dimensions, and includes at least one receiver attached to an extension of a cylindrical support rod. A cylindrical pipe fitted with another wave receiver is rotatably fitted into the support rod, and the combination of these wave receivers allows for a tertiary wave in the direction of the central axis of the support rod, any direction perpendicular to it, or both. This device is designed to measure each sound intensity in the original direction, and examples thereof will be explained in detail below with reference to the drawings.

In FIG. 1, reference numeral 11 denotes a wave receiver, which is attached to the support rod 3 via a receiver support 21. The support rod 3 is secured to a shipboard structure 5 by a securing section 4. Reference numeral 6 denotes a cylindrical pipe, to which a receiver 12 is attached via a receiver support 22. Reference numeral 7 denotes a stopper attached to the support rod to prevent the pipe 6 from falling off. 8

Figure 2 shows an embodiment in which the present invention is applied to three-dimensional sound intensity measurement, in which a receiver 13 is placed in addition to the receiver 11 on the extension of the central axis of the support rod, and the By arranging the receiver 11 and the support rod 3 on the same plane perpendicular to the center axis, the acoustic intensity component in the direction of the center axis of the support rod 3 and the acoustic intensity component in the plane perpendicular to the center axis of the support rod 3 can be reduced. Since sound intensity components in two orthogonal directions can be measured, three-dimensional sound intensity can be determined by vector synthesis of the components in these three directions.
