Advanced digitalization of acoustic footprints in historical theatres for preservation and reconstruction

Abstract

This paper presents an innovative procedure for the advanced digitalization of acoustic footprints in historical theaters, aimed at preserving their acoustic characteristics for future reconstruction in the event of disasters. The methodology incorporates laser scanning and acoustic simulations with ODEON, followed by a novel archiving process that ensures the long-term availability of detailed acoustic models. We propose a systematic approach to creating a geometric and acoustic model that includes multi-scenario simulations to capture the acoustic response under varying conditions. The validated acoustic model is then archived in interoperable formats to facilitate future use and reconstruction. By documenting the acoustic parameters alongside the geometric data, this approach not only preserves the theater’s acoustic legacy but also provides a robust framework for future restorations. The results of this study demonstrate the efficacy of this method in maintaining the historical integrity of acoustic responses, ensuring that future generations can experience the unique acoustic characteristics of these sites of cultural heritage.
