underwater sound measurement的意思|示意

Based on measuring the cross-spectrum density of sound pressure between two hydrophones, the facility for underwater sound intensity measurement is investigated and designed.

基于双水听器互谱测量法，研制的水声声强测量设备可用于测量水下声源产生的声场中任意点的声强量值或任意面上的声强量值分布。

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.

脉冲声技术是一种很常用的水声测量技术，但由于脉冲声存在着瞬态过程，严重影响了它在低频下的使用。
