Broadband vibroacoustic fingerprint of a historic building chamber concert room in Napoli (Italy)

Abstract

Tangible and intangible elements of cultural heritage are interconnected in supporting the growth of sustainable and resilient urban lifestyles. In the case of sites of historical and archaeological relevance, some spaces were conceived and designed to host specific practices (e.g., religious, musical, theatrical, political, etc.). However, the reasons for designing those historical spaces in a certain way often remain substantially unknown, due to the lack of available documental sources related to their design and planning. In the case of intangible vibroacoustic characteristics of a certain space, part of this information may be retrieved by specific measurements. For this reason, we have started a preliminary experimental activity, aimed at characterizing the vibroacoustic fingerprint, i.e. the vibro-acoustic site-specific features, of a private chamber concert room, located inside a historic building in the center of Napoli (Italy). For such a purpose, acoustic measurements were integrated with broadband vibration measurements though a dedicated monitoring system for identifying the vibroacoustic fingerprint of the room, using time-series and frequency-based analyses.
