Comparison of the 3D acoustics of the Roman performing arts spaces in Pompeii

Within the SIPARIO Project, a project founded by the European Community and lead by the Region Emilia Romagna, a specific acoustic survey has been carried out in the archaeological site of Pompeii. The ancient city includes three different Roman performing arts places: the theatre, the Odeon and the amphitheatre. The surveys have been conducted with differ ent types of equipment: monoaural and binaural microphones, B-Format (4 channels) microphones and 32-channels probe (EigenMike EM32). This paper reports the most important outcomes obtained from the measurements, by including 360° acoustic maps that allow a study and the visualization of the early and late reflections. The panoramic acoustic maps have been compared among the above cited sites, and analyzed with reference to the standard requirements outlined by ISO 3382.
