On the acoustics of “Argentina” and “Costanzi” Opera Houses in Rome by means of 3-D maps representation

Abstract

The acoustics of Italian-style Opera Houses has been widely studied in the last 30 years, especially after the burning of the Teatro La Fenice in Venice in 1996. Starting from that disaster, the acoustics of these important buildings became a priority, especially for storing as much information about their acoustics as possible. The recent war events in Ukraine have underlined the importance of these acoustics for a proper reconstruction of theaters, and especially Oper Houses. This paper analyzes the acoustics of the two most important opera houses located in Rome, i.e., the “Teatro Argentina” and the “Teatro Costanzi” (also called “Teatro dell'Opera"). Both the theaters are located in the very city center of Rome and have a strong artistic activities. In both the cases, no info about their acoustics are available among the scientific community. This paper describes the most important results obtained measuring their acoustics using monoaural, binaural b-format microphones. Moreover, in order to determine 3-D acoustic maps, an EM32 Microphone from MHAcoustics was used for capturing sparial RIRs and mapping early reflection in a 360 pictures.
