The investigation of the mechanical properties of stone commonly adopted in old buildings in the south of Italy by means of ultrasound analyses is the subject of this work. In particular, starting from the analysis in the time and frequency domain of the ultrasonic signals, the correlations between the ultrasonic parameters and the stone’s mechanical properties are investigated. Finally, the influence of normal stress on the ultrasonic parameters is examined.
