METHOD OF IDENTIFYING SOURCES OF ACOUSTIC EMISSION Russian patent published in 2020 - IPC G01N29/14 

Abstract RU 2737235 C1

FIELD: physics.

SUBSTANCE: invention can be used for identification and classification of acoustic emission sources (AE) at controlled objects. Essence of the invention lies in the fact that the method of identifying signals AE is based on determining the relationship between the numerical value of energy calculated for the wavelet decomposition component of the signal AE and the Fourier spectrum of the wavelet decomposition component and a parameter characterizing the type of material destruction, taking into account the distance from the source to the AE signal receiver.

EFFECT: high reliability and possibility of identifying sources of acoustic emission generated by different types of sources AE, characterizing destruction of materials and located at different distances from receiver AE.
