Abstract: The protection of ancient, weathered and soon wasted by carelessness national building heritage needs to develop non destructive techniques to diagnose the state of the structures.
Among the different non destructive diagnostic methods, sonic inspection's methods seem to be very suitable for evaluating a buildings condition, because they give information with immediacy, rapidity and relatively low cost. The sonic surveys give information directly related to structure's elastic parameters, crucial for inspections of structures' stability and lastingness, with high penetration depth. Therefore, sonic methods clearly seem to have a very good capability to analyse either heterogeneous materials, such as stone masonry, characterised by strong attenuation, and ancient carrying elements, featured by high thickness.
In the present paper results of sonic surveys, extensively carried out on several limestone masonry buildings of the historical nucleus of Cagliari (Italy), are reported and discussed.
Moreover, sonic methods have been carried out on a full scale limestone masonry with known anomalies, and results have been compared to those derived from tested historical buildings.
