2021-1-29  The acoustic emission signal propagates well through solid material. Acoustic emission waves are either shear or longitudinal. Any internal surfaces, i.e., cracks or inclusions, will distort and damp these waves. A single grain in a conventional grinding wheel will produce an acoustic emission burst propagating through the wheel.
