ACOUSTIC EXPLORATION OF THE TEATRO DELL'OPERA OF ROME

The opera houses are considered the most representative buildings for live shows. Conservation, restoration, and preservation are all activities that should be carried out with acoustics as a more fragile discipline for intangible cultural heritage. This paper regards the measurements taken inside the Teatro dell'Opera of Rome by following the requirements of ISO 3382-1. The post-processing analysis of the recorded sound signals allows the calculation of the acoustic parameters. Along this approach, a more innovative is used by employing a multi-channel spherical array microphone and creating overlay videos of impulse responses (IRs) to visualize the interactions between the sound waves and the room's architectural elements. The study results show that Teatro Rome still has excellent acoustics over time, compared to contemporary opera houses.
