Virtual Acoustics of the Roman Theatre of Italica (original) (raw)

Classic outdoor theatres have special significance in the universal, cultural and architectural heritage. These scenic environments have undergone acoustic research in ERATO European project with basic purposes of recreation of associated intangible heritage and for their adaptation to contemporary cultural performances. In this work, the Roman theatre of the archaeological site of Italica (Seville) is studied by means of acoustic simulation, which responds to the classical scheme: cavea, orchestra, scenae, four-sided portico, and a capacity for 3,000 spectators. Throughout this paper, the creation process, adjustment, and validation of the 3D model of the theatre for simulating its sound field is analysed, which is based on the experimental measurement of reverberation time. The initial model, once validated, is modified to assess the acoustic impact of various proposed interventions.
