A study on the spatial sound propagation characteristics of the Argentina Theater in Rome

The "sound" of cultural heritage is often neglected and fragile, but it has the same historical value and research significance as tangible cultural heritage. The current study was driven by investigating and preserving the acoustic characteristics of the Teatro Argentina, one of Rome's historic theaters. In this paper, the impulse response (IR) of several of the main auditory parameters identified by ISO 3382-1 during the investigation was first recorded using standard methods. Secondly, an innovative acoustic research methodology was used to show the direction of the arrival of the sound rays and to visualize the sound intensity. This methodology improves understanding of the early and late reflections of sound-hitting elements of architecture.
