Add to ORKGPresently, most acoustic emission applications in nondestructive testing involve placing transducers on a large structure, a bridge or hydrocarbon cracking pressure vessel, then loading the structure and listening for the burst-type acoustic emissions that ensue, and ,finally using triangulation to locate the flaws whence came those bursts. This technique is very effective at locating defects, and that means that the typical, most studied acoustic emission parameters are just the number of events, the event rate, and to a somewhat lesser extent, the maximum amplitude . It might be the root mean square. amplitude, or some other amplitude that characterizes the acoustic emission, or an amplitude distribution, that is, the number greater than ...
