Abstract
The term “acoustic emission” means radiation processes of exertion waves which are produced by internal sources located in the thickness of material under investigation. Acoustic emission method is used as a means of analysis of materials, constructions, productions control and diagnosis during operating time. Energetic parameters as the acoustic emission energy itself may be obtained only based on the whole spectrum analysis. It is strictly contraindicated to measure signal energy in narrow band, naming such measures as “energetic parameters”. Energetic parameters as the acoustic emission energy itself may be obtained only based on the whole spectrum analysis.
