Metrological Aspects of the Process of Recording the Energy Parameters of the Acoustic Emission of Substances

Analysis of energy and spectral characteristics of acoustic emission signals from the Hsu-Nielsen source

“…More detail questions of attenuation calculating of AE signals described in [17]. Figure 3 demonstrates the results of spectral analyzing for one realization of experiment.…”

“…The slope of the approximating line is very clearly characterizes the graph of attenuation. A positive value of slope, according to [17], shows that the analyzed signal is a signal from the structural changes within the control object but not an interference signal. Other secondary parameters such as offset and standard deviation of attenuation can be also used for deeper research of the attenuation.…”
