Quantitative acoustic emission (AE) techniques can be used to monitor crack growth and to deduce microfracture mechanisms in quasi-brittle materials. Multichannel data acquisition systems are used to record the AE waveforms. The results of a quantitative AE analysis are quite sensitive to the interpretation of the recorded waveforms. Several techniques are presented here which facilitate AE data interpretation. Included are noise reduction and signal enhancement methods, and time domain deconvolution methods which are used to recover microcrack fracture parameters.
