摘要：

Aim of this paper is to asses the theoretical and practical feasibility of a method for the voids detection In brick masonry by an ultrasonic testing. The wall itself acts as a waveguide for a properly generated ultrasonic elastic wave; this makes possible the Inspection of relatively large portions of masonry. The analysis of the waveform of the displacements measured by an array of couple of sensors (typically three or four) allows the detection and the localization of defects. The proposed method has been validated by a measurement campaign on masonry test specimen of different texture and thickness.
