Abstract

The “Teatro Comunale” (City Theatre) in Bologna is an Italian opera house of the 18th century, designed by the famous architect Antonio Galli Bibiena. Largely built in masonry, it has been only partially restored and altered several times, but never destroyed and rebuilt. The study of its acoustics, while interesting for itself, offers the opportunity to investigate the role of the boxes, which constitute the most evident characteristic of Italian opera houses. The study was carried on at first by measurements, acquiring binaural impulse responses in the stalls and in the boxes, and then by computer simulation, modelling also some changes which cannot be done in the real hall. The measurements revealed clear differences between the listening quality in the boxes and in the stalls, especially regarding ITDG, clarity and IACC. Computer simulations show how the sound field in the historical theatre could be if the sound absorption of the boxes were changed, adding some velvet curtains, as was done in ancient times, and clarify the effects of the cavities which constitutes the boxes.
