【摘要】 采用两个全向性的水听器组成的声强传感器,借助于日本小野测器公司的声强测量系统(CF-500)和(CF-502),测量了水中声强及声功率,并作了双水听器声强传感器的方向性测定和测量误差分析。实验证明了采用双水听器声强法在水中进行声功率测量是有意义的。更多还原

【Abstract】 With two omnidirectional hydrophones and sound intensity measuring systems CF-500 and CF-502 of Japanese ONO SOKKI Co.,sound intensity and acoustic powerunder water were measured.The directivity curves of the dual-hydrophone systemhave been obtained,and its error analysis has been made.It is shown by experimentsthat the determination of sound power under water through the measurement of soundintensity with a dual-hydrophone system is available in practice.更多还原
