Brief：Acoustic emission is the phenomenon of acoustic waves generated and propagated in the material when the material is under deformation.
What is acoustic emission (AE)？
Acoustic emission is the phenomenon of acoustic waves generated and propagated in the material when the material is under deformation. Acoustic emission is a common physical phenomenon. A typical example can be the sound of breaking a pencil. But most acoustic emission signals are too weak to be heard by ears. The technology of using equipment to detect, record and analyze acoustic emission signals and find the acoustic emission sources is called acoustic emission testing. Acoustic emission testing is one of the non-destructive testing (NDT) methods.
Wireless valve leakage monitoring
In particular, AE is occurring during the processes of mechanical loading of materials and structures accompanied by structural changes that generate local sources of elastic waves.This results in small surface displacements of a material produced by elastic or stress waves generated when the accumulated elastic energy in a material or on its surface is released rapidly.

The waves generated by sources of AE are of practical interest in structural health monitoring (SHM), quality control, system feedback, process monitoring and other fields. In SHM applications, AE is typically used to detect, locate and characterise damage.
