- Abstract
To extensively characterize heterogeneous structures such as mural paintings on site, an experimental method and the relative device, denominated Acoustic Energy Absorption Diagnostic Device, were purposely implemented. The system provides acoustic images of the painted surface, localizing detachments and flaws where the acoustic energy absorption is considerable. Different phases from laboratory validation on suitable models, functional to the patenting process, to the field validation on real frescoes, glazed ceramic tiles and panel paintings, from the customization of the device's configuration, to the study of important metrological aspects were oriented to the realization of a suitable diagnostic tool for helping conservator scientists in the preventive field diagnostics. In the present paper the overall experience in the development of the acoustic imaging technique is reviewed in order to present some reflections regarding the way to support innovation in the Cultural Heritage domain. Few key factors for the advancement of innovative technologies are identified: a suitable metrological approach for the assessment of the method's applicability; the construction of a joint environment for a systematic and participated field experimentation; an accurate planning of significant comparisons between different methodologies; a constant attention towards protocols and procedures optimization as well as towards technical innovations.
