Based on measuring the cross-spectrum density of sound pressure between two hydrophones, the facility for underwatersound intensity measurement is investigated and designed.
The measurement of radiation noises from an underwater structure body and identification and location of noise sources were carried out by using a sound intensity measurement system .
通过用声强测量系统对水下大型结构体进行了辐射噪声声功率的测定以及噪声源的识别和定位的实验。

Sound pulse technique is often used in the underwater acoustic measurement, but it has transients, so it can not be used in low frequencies.
