Standalone detector for vibroacoustic heritage monitoring

This paper describes the results of preliminary application tests for a stand-alone prototype data acquisition system. The system was developed for monitoring and characterizing the vibroacoustic landscape and, in particular; the vibroacoustic heritage, such as music instruments or performing spaces. The tests, performed on a building in the historical center of Napoli, show a possible interconnection between acoustic and displacement signals, as external forcing of the monitored structure, with exchange of the cause-and-effect roles, especially at low frequency.
