The mechanism of this instability is based on the cycle of acoustic waves between their corotation radius and the shock.
这种不稳定性的机制是基于声波在其同心圆半径和冲击之间的循环。

"Shock waves are acoustic waves that create pressure that can be focused," says Medispec's Gil Hakim, the company's director of new product development.
“冲击波是一种声波，它形成可以聚焦的压力，”Medispec公司的新产品开发总监吉尔哈姬姆说。

When a sound wave strikes the spheres at one end of the acoustic lens, the sound gets converted into a type of shock wave known as a solitary wave.
