The Rossini Theatre of Lugo (RA) was built in 1757- 60, following the design of Ambrogio Petrocchi and completed in the stage, seating and balconies by Antonio Galli Bibiena. The Masini Theatre of Faenza (RA), was built in 1780-87, following the design of Giuseppe Pistocchi. The two theatres have never been measured and they represent a case study to evaluate the reliability of the numerical simulations of 18th century Italian Theatres. Impulse responses with different source-receiver combinations have been acquired, and monaural descriptors have been calculated. An hybrid ray-tracing software (Odeon) has been used in order to test the same monaural parameters, following similar studies from literature. Considering that the two theatres have comparable general aspects (volume, number of seats, materials...) but they have different geometrical elements and surface treatments that influence the acoustic field, different hypotheses on the scattered field and different resolution of numerical simulation have been compared. Thanks to the multitude of measured positions, a point-topoint comparison between the simulated and measured parameters permitted the validation of both numerical models.

Abstract
The Rossini Theatre of Lugo (RA) was built in 1757- 60, following the design of Ambrogio Petrocchi and completed in the stage, seating and balconies by Antonio Galli Bibiena. The Masini Theatre of Faenza (RA), was built in 1780-87, following the design of Giuseppe Pistocchi. The two theatres have never been measured and they represent a case study to evaluate the reliability of the numerical simulations of 18th century Italian Theatres. Impulse responses with different source-receiver combinations have been acquired, and monaural descriptors have been calculated. An hybrid ray-tracing software (Odeon) has been used in order to test the same monaural parameters, following similar studies from literature. Considering that the two theatres have comparable general aspects (volume, number of seats, materials...) but they have different geometrical elements and surface treatments that influence the acoustic field, different hypotheses on the scattered field and different resolution of numerical simulation have been compared. Thanks to the multitude of measured positions, a point-topoint comparison between the simulated and measured parameters permitted the validation of both numerical models.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
