摘要：

In this paper, investigations on the applicability of the 3D pressure-velocity sensor in the sound field for acoustic measurement of building are presented. First, a calibration method for the sensor using an acoustic tube is proposed. Next, the measured values from the sensors installed near field of the boundary in the sound field of the floor impact sound are compared with those from the vibration acceleration pickup installed on the boundary. Finally, measurement results of time response of 3D particle velocity and instantaneous sound intensity in the field in wooden and RC buildings are shown. © 2023 Architectural Institute of Japan.
