Full text linkIn 1967, the Cagliari municipality started building a new Opera House, to replace the 19th century theatre,
destroyed during the Second World War.
After an initial stage, the works were interrupted due to lack of funds, and restarted only in 1985. Only
when the works were taken up again was the acoustic consultant contacted, who therefore intervened on
an already partly constructed building. It soon became clear that the room shape was problematic from an
acoustic point of view.
Thus, a 1:50 scale model was built on which the first reflection acoustic field was studied. A series of
experimental measurements was also carried out inside the structure. From these experiments it became
clear that the shape of the hall needed to be changed. In particular, the inclination of the side walls had to
be varied in order to increase the number of useful reflections in the central area of the main floor.
The work inside the hall was finished in 1993, but the stage equipment necessary for the production of
operas is still missing. In order to make it possible for the theatre to be inaugurated, an acoustic chamber
was designed and built. This means that the hall can be used for symphony concerts.
The theatre was inaugurated in September 1993 with a concert conducted by Riccardo Muti.
In this paper, the Authors present the experimental results obtained throughout the whole project
development, until the present situation with the acoustic chamber

Noise and vibration control in multiplex cinemas
No full textNoise and vibration control requirements for multiplex cinemas are normally very strict. Inside the rooms, low background noise and vibration levels below the perception threshold need to be guaranteed. The noise and vibration sources could be external (road, rail and air traffic) and/or internal (adjacent cinema rooms, escalators, car parks, air conditioning plants, people in public areas). Every possible source needs to be considered in order to reduce the noise and vibration generated and transmitted through the building. In the paper an example of noise and vibration control design and verification is presented. The prescriptions of the company were very strict due to the particular environment in which the building was designed: a few meters from the railway and close to Genoa Airport, the industrial area and the dock area
