Theatre “Morlacchi” in Perugia: Determination of the Acoustic Characteristics and Proposal of Improving Quality Solutions

This paper deals with the evaluation of the acoustic quality of the theatre Morlacchi in Perugia, Italy; some improving solutions have been individuated too. Acoustic quality parameters have been measured by means of a data processing system. Sound pressure levels due to a dodecahedral source placed on the theatre stage have been measured for 40 measurement points. Data acquisition system has processed the measured levels in order to evaluate the theatre acoustic quality parameters. Measurement results have been compared to their optimum values. The comparison has shown the necessity to improve the theatre acoustic quality. Simulations have been carried out by means of a numerical code in order to individuate improving solutions. Some different methods have been proposed for prose spectacles and concerts. Simulations has shown an approximately 22% increase for STI and RASTI parameters by using the proposed improving quality solutions.
