摘要疏水球从一定高度自由释放入水后形成空腔，本文利用水听器与高速摄像机同步，直观地演示了疏水球入水后产生的水声。可以发现所记录的水下声音的声学信号包括两个主要频率。一个值得注意的发现是，较高的主频率的声音可以激发的呼吸模式后，空腔夹断球后方的剩余气泡。此外，较低频率的声音被预测为由球体的冲击引起的自由表面的振荡所驱动。图形摘要
AbstractA hydrophobic sphere, freely released from a certain height, entering water makes a cavity behind it. This paper visually demonstrates underwater sound produced by the water entry with the use of a hydrophone synchronized with a high-speed camera. The acoustic signal of the underwater sound recorded can be found to include two predominant frequencies. A remarkable finding is the fact that the higher predominant frequency sound can be excited by the breathing mode of a residual bubble behind the sphere after the cavity pinching off. In addition, the lower frequency sound is predicted to be driven by the oscillation of the free surface caused by the impact of the sphere.Graphical abstract
