How does the AE leak detector work? (method)

I want to know the method of leak detection using acoustic emission
Thank you

Re: How does the AE leak detector work? (method)
As with many questions you need to specify the application. AE is a transient wave generated by a source mechanism. It is the origin of the source which affects how and when you can detect the signal along with issues such as wave propogation and attenuation. In leak detection the source is often turbulence by the passage of gas or liquid through a hole (simplistic). This generates an AE signal which then can be detected by correctly placed sensors which may be as simple as a hydrophone or a piezo resonant sensor.
The source origin mechanism may be more complex than described here and so may the sensor solution but that is basically what happens. if you need more please email me directly.

es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.
