摘　　要：在水池中利用声压水听器和矢量水听器对实验模型低速入水产生的溅落声进行了一系列测量实验,对低速物体溅落声信号的波形特征、声源强度随入水角的变化规律以及频谱特性进行了初步分析,并给出了一些实验结果。The sound produced by the splashes of low-speed water entry of low-speed experimental model are measured using pressure hydrophone and vector hydrophone in a water tank. We elementary analyzed the characteristics of sounds of splashes of low-speed water entry, such as the characteristics of time wave, relationship of the intensity of sound and angle of water entry of experimental model, and the characteristics of the spectrum of the impact and bubble pulses. The experimental results are given in the paper.
