The city of Rimini, North East of Italy, has completed in 2018 the realization of the New Teatro Amintore Galli, which was partially damaged and demolished during the Second World War. The new theatre recalls the original architectural idea of the existing theatre (designed by Luigi Poletti), but improves the technological equipment, including noise insulation and acoustic quality. However, some constraints have conditioned the original acoustic design, especially the new archaeological area that was inserted underneath the ground floor, which required to change the original wooden structure into a concrete-based one. The acoustic design of sound quality included the study of the orchestra pit, the acoustic absorptions of tissues in the main hall, the measurements sound absorption of seats. Since the shape and the characteristics of the material (marmorino stucco), might cause focalization, a special care was reserved design diffusing panels located in the main hall. The paper focuses the acoustic design of the theatre especially considering the diffusing panels. Starting from the drawings, the paper will examine the results of the scattering and diffusion measurements on the panels, as well as the overall sound quality of the theatre after the opening (scheduled for August 4th, 2018).
