The Auditorium Toscanini of the city of Parma was created following an important work of requalification of pre-existing industrial structures. They were reconverted into an Auditorium thanks to an ambitious project of the architect Renzo Piano. Also the rehearsal space of the orchestra was obtained from the requalification of an ancient industrial building. It was acoustically adapted by the means of recycled rubber sound-insulating panels inserted in the walls. In one of the temples of the Italian orchestral excellence, recycled rubber has given an excellent sound performance, even compared with the extremely high standards required by the professionals of the Philharmonic society “Arturo Toscanini”.
