This work deals with a specific method of non-destructive testing - acoustic emission. The theoretical part of the article is focused on the underlying principle of this method and its applicability. The experimental part is focused on the research of pressure resistance in mineral feed using acoustic emission. Mineral feed is a condensed cube of rock salt (sodium chloride) with supplementary minerals, which is fed to livestock and game to supply the mineral elements necessary for their health and condition. Acoustic emission gives the overview of internal changes in material structure. With use of specific software we can interpret the acoustic signal and identify the current state of material integrity in real time.
