The interpretation of data measured by Acoustic Emission (AE) is largely based on empirical correlations between the respective characteristics of the source and the measured signal. The main limitation is that changes due to the acquisition chain are not well known. Therefore, the aim of this work is to build a quantitative relationship between the AE sources and the detected signal by unravelling the effect of the different stages of the acquisition chain. For this purpose, an AE modelling, in which each part is considered individually, is carried out. This will serve to understand the effects of different parameters on the signal waveform, such as the type of damage, the geometry of the specimen and the effect of the piezoelectric sensor.
