Influence of Geometric Proportions, Size and Materials on the Acoustic Field in Italian Opera Houses
Going on with the study about Italian Opera Houses, and in particular about the influence of the architectural design on the acoustic quality of the hall, measurements of the usual acoustical parameters have been developed in two theatres designed by the same Architect Antonio Galli Bibiena, namely the Municipal Theatre in Bologna and the Scientific Theatre in Mantua. Both the two theatres have quite the same shape, but are different in size and choice of materials: the first one is all in masonry, while the other is quite all in wood, or so it was before the refurbishing works that introduced many structures in reinforced concrete. The elaboration of so many data is already accomplished and now some comparisons and results are already available. In particular, the correlations between some characteristic size and the spectral response to a swept signal with all audible frequencies are presented here. Some considerations about the influences of materials and shape on the IACC and EDT objective parameters are also presented.
