Il progetto SIPARIO intende creare e rafforzare una rete tra Teatri d’Opera in Emilia-Romagna e l’Europa mediante la riproduzione virtuale delle performances in una sala d’ascolto dedicata. A questo scopo, verranno implementate le nuove procedure di misurazioni di risposta all’Impulso 3D negli ambienti chiusi per determinare le caratteristiche della propagazione del suono, e contemporaneamente verranno implementate le teorie più evolute di virtualizzazione acustica tramite Auralizzazione 3D consentendo di apprezzare, approfondire e divulgare le informazioni acustiche su questi edifici. La spazializzazione 3D e la realtà virtuale aumentata immersiva potranno consentire di assistere virtualmente agli spettacoli.

Music, Sound and Architectural Acoustics are internationally recognized as an important Intangible Cultural Heritage. Italian-style Opera-houses are among the most important historical building in Europe, some of them are included in the UNESCO heritage list. This research aims to link several Opera Houses in the Emilia Romagna region to the European network of historical theatres, adding the information about sound propagation to the historical descriptions already available. The measurements of proper Impulse Responses (IRs) in these opera houses allow understanding the acoustics of these important spaces. Besides, it allows the 3D auralisation (i.e. virtual playback of the sound distribution in the rooms) in specific listening rooms, preserving this information for the posterity. The team at University of Bologna has developed a new method to measure the spatial (3D) IRs in rooms that allows the complete spatial sound analysis. It is aimed at creating easy-to-understand images and videos showing the direction-of-arrival of the room reflections, and storing this information for the posterity. The method is based on the measurements of the IRs by means of a set of probes. The first microphone (mono omnidirectional) allows determining the conventional monoaural acoustic parameters and is considered as a "reference" microphone. The second probe consists of a binaural microphone, used during binaural or stereo auralisation. The third one consists of a 4-channel B-format probe, used during Ambisonic auralisation. The forth one consists of a compact microphone array employing a much larger number of transducers, that is used to measure and playback higher-order 3D Impulse Responses in a spherical and cylindrical array. Combining these methods, it is possible both to listen to the sound effects in the opera houses and watching the video containing all early reflections propagation in a panoramic background image of the room.
