Acoustic emissions are stress waves produced by sudden movement in stressed materials. The common sources of acoustic emission are crack growth and plastic deformation. Unexpected movement at the source produces a stress wave that releases out into the test object and excites a sensitive piezoelectric sensor. As the stress in the material is elevated, emissions are generated. The signals from one or more sensors are amplified, measured for display and interpretation.
