When gas or air passes through a small hole, turbulence is generated, and the turbulence generates ultrasonic waves. Therefore, when air leaks into the vacuum easily or the pressure vessel leaks into the outside air, ultrasonic waves with strong directivity are generated.

When a container or pipeline is filled with gas and its internal pressure exceeds external pressure, significant pressure differentials cause gas to rush out through any leaks. If the leak is small and the Reynolds number is high, the escaping gas creates turbulence.
