Acoustics exploration of the Galli theatre of Rimini after the restoration works of 2015

The acoustic studies of the Italian Opera theatres have been improved their accuracy by the development of a new generation technology. An acoustic survey has been undertaken inside the Galli theatre of Rimini in order to show the acoustic parameters as required by the regulations (ISO 3382-1). Furthermore, a multichannel spherical array microphone has been employed to add value to this acoustic investigation by illustrating the impulse response (IR) through an overlay video. The outcomes of this additional provision have been recorded with some snaps related to different moments of the IR decay. The authors of this paper illustrate also a brief history of the Galli theatre of Rimini, including the description of the architectural features that characterize this important Opera house.
