It has been shown in acoustic emission literature that the distance between a possible cracking event and a receiver is affecting the signal parameters providing a wrong image of the real fracture characteristics. In this study, lab-scale experimental tests on masonry components are performed in order to determine the disturbance of the acoustic emission wave properties and verify the experimental observations via numerical wave propagation analysis. The investigation is extended to different geometries including “couplets,” “triplets” and masonry walls. The simulations allow to understand, verify and predict the acoustic emission signal properties alterations in many different types of masonry experiments as well as the correct characterization of the fracture mode.
