Abstract
The study of the sound field inside ancient theatres is one of the targets of the EU project ERATO. Within this project several campaigns of acoustical measurements were done both inside existing ancient theatres and on a scale model of an ancient theatre expressly build for the scope. The scale model was conceived to trace the evolution of theatre acoustics throughout the centuries. The theatre of Siracusa in Italy was selected to build a wooden 1:20 scale model. In fact substantial architectural changes were implemented in this theatre in its passage from Greek to Hellenistic and finally to Roman style. The cavea was enlarged and an ambulacre with columns was added in its upper part. The orchestra was also enlarged and a big stage building was built. The model has a modular structure that can be adjusted to the different periods so that the evolution of acoustics can be investigated. For the acoustical measurements two types of sources were used: a miniaturised dodecahedron made of p...I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
