Features of construction the registration system for acoustic emission signals

The major problems of the nondestructive inspection acoustic emission method are analyzed in the article. The inappropriateness of the analysis method in the narrow band of frequencies is shown in the article. The comparative results of the acoustic emission signals spectral analysis for different types of materials are given as an example. The necessity of using spectral analysis methods to increase the accuracy and reliability of results is demonstrated.

Keywords: non-destructive testing, acoustic emission, spectral analysis, the energy of the acoustic signal.
