Abstract
The distinctive features of the form of the amplitude distribution of acoustic emission (AE) pulses and the results of determination over a broad dynamic range are considered. For the power-law model of the amp litude distribution and the Poisson model of the flux of AE acts we as sess the reliability and obtain the conditions for a maximum of spurio us amplitude noise to appear. The block diagram is given for a device to measure the degree of AE pulse overlap and enhance the reliability of the results obtained by the AE method of inspection and diagnostics .
