Chamber Music (acoustical) - The primacy of Italian manufacturers
by Enrico Parola
from Corriere della Sera - June 19th, 2021

"Today the musicians are surrounded by real wooden caskets, the acoustical shells, with platforms, side walls and 'ceiling'. Almost all Italian Theatres have them: San Carlo in Naples, Petruzzelli Theatre in Bari, Scala Theatre in Milan, Municipal Theatre in Bologna"

"Many of them are made by Suono Vivo, a Padua company that is a worldwide excellence: the Bolshoi in Moscow, the London Covent Garden, the An der Wien Theatre and the SemperOper in Dresden, the Opéra Bastille and Garnier in Paris, Berliner Philharmoniker, in 2008, to play a piece by Stockhausen at the Tempelhof airport, which included 109 performers and 3 Conductors: the technicians managed to reduce the sound reverberation from 8 to 2.5 seconds.
Still for the Berliners, Suono Vivo created the acoustical shell to play in Waldbuhne: the design of the open-air transparent side panels allowed to open up a further frontier to the combination of different beauties, sound, art and nature. Just think of the Teatro Grande in Pompei or the amphitheatres of Pozzuoli and Pola, the Rocca Brancaleone for the Ravenna Festival or Torre del Lago for the Puccini Festival, the Redipuglia Memorial and the churchyard of the Milan Cathedral for the concerts of the Filarmonica della Scala."
