The various techniques described are used for such purposes as characterizing the acoustic emission from particular materials and processes, eliminating noise, checking wave propagation properties of engineering structures and applying the results to test design, loading that will optimize the acoustic emission data from a structure without causing appreciable damage, and locating acoustic emission sources either roughly or precisely. The third edition reprints information that remains current, includes new material that brings theory into focus and demonstrates the potential of acoustic emission testing as a quantitative nondestructive testing tool, and increases the number of contributors from outside the US.
