Dipartimento Ingegneria ed Architettura (DIA) & Dipartimento di Discipline Umanistiche, Sociali e delle Imprese Culturali (DUSIC) At UP the study of spaces for performing arts has a long history, linked to the city’s cultural heritage strongly interconnected with the history of opera and opera houses. UP is cooperating with local musical institutions and the municipality in a number of initiatives, culminating in international events such as the Festival Verdi, and the designation of Parma as the Italian Capital of Culture 2020. The most evident proof of success of this cooperation between the two departments of UP and the municipality is Casa della Musica: a performing space (both indoor and outdoor), museum, and the research lab of acoustical engineering of DIA. It hosts the archives of the Verdi Foundation, offices and classrooms for the Musicology group of DUSIC, and Casa del Suono, an exhibit of ancient and modern sound reproduction devices. It also houses an advanced research centre equipped with a 189 loudspeakers WFS system and 4 full-HD video projectors for fully immersive audio-visual reproduction, and an installation for virtual acoustics performances featuring a dome with 226 loudspeakers, employed for live concerts of electronic music.

• Farina, Angelo (PI) : Full Professor of Environmental Technical Physics. Angelo conducted research in almost all the fields of Acoustics, and particularly he worked on digital signal processing techniques for acoustical measurements and audio effects, and on numerical models for the sound field propagation in closed and open spaces. In more detail, he developed new measurement techniques, based initially on the use of binary pseudo-random signals (MLS) and subsequently on exponentially-swept sinusoidal signals; these allow for the easy measurement of the sound propagation in working places, outdoors, and in concert halls and auditoriums. Another research topic has been the usage of transducer arrays: loudspeakers, microphones, hydrophones. Employing advanced beamforming techniques, Angelo managed to synthesize virtual loudspeakers and virtual microphones with arbitrary directivity and aiming, which are used for sound recording and reproduction, and for acoustical measurements. Angelo has coded several software tools for the simulation of sound propagation indoors and outdoors and for automating impulse response measurement and processing, namely the Ramsete, Disia and Aurora packages.
• Antonella, Bevilacqua : Student researcher at the University of Parma. The most recent project which she was involved on is named Sipario, related to the virtual reconstruction of artistical performances executed inside the Italian Opera theatres through an immersive listening playback. The Sipario project aimed to record and reproduce concerts and shows in such a way to appreciate both the artistic experience and the acoustic information of the architecture. The auralization has been realized by using MIMO measurements, followed by the wavefield analysis and Ambisonics spatial sound techniques, rendered in 3dof. Her most recent publications are based on the outcomes obtained by this research activity, involving the acoustic studies of approximately 13 theatres located across Italy, mainly built between 17th and 18th century, most of them protected by international organization (e.g. UNESCO). Now she is focusing the research upon the ancient theatres of Roman and Greek style, to include also amphitheatres and odeia characterised by geometrical features that influence in a particular way the behaviour of the soundwaves. Beside the auralization, previous research studies undertaken by Antonella were focused on noise and vibration analysis of activity in fitness facilities, including drops of hard heavy weights as a common source of disturbance in mixed-use building type. Based on tests applied on different thickness of selected rubber flooring tiles, based on the variabilities of free dropping height and weight, a certain floor vibration reduction (i.e. delta-LV) has been obtained over a specific frequency range, reasonably independent of structure typology.
