L'Auditori, Barcelona
L'Auditori Barcelona was designed by Pritzker Prize winning architect Rafael Moneo and was inaugurated in 1999. Since opening, the hall has been the home of the Barcelona Symphony Orchestra and the National Orchestra of Catalonia and became the home of the Barcelona Municipal Band in 2007. These two historic ensembles have played a fundamental role in Barcelona's musical life since the 19th century.
Along with the 2 199-seat concert hall, Sala 1 Pau Casals and several smaller chamber music halls, L'Auditori centre is also home to the Escola Superior de Música de Catalunya (ESMUC) and the Museu de la Música.
The Sala 1 Pau Casals concert hall, while considered to have good acoustics for the audience, was reported to have challenging on-stage hearing conditions for musicians. In January 2022, Kahle Acoustics was therefore invited to conduct acoustic tests to investigate the on-stage hearing conditions and to determine how the stage acoustics in Sala 1 Pau Casals could be improved. Listening tests using temporary reflection and absorption surfaces were carried out, with feedback gathered from the musicians in real-time as alterations were made. These tests resulted in a suite of measures to improve on-stage hearing conditions, including suspended reflectors, acoustically optimised side balcony fronts for musical cross-communication and additional absorption areas to improve orchestral balance and reduce loudness. Based on Kahle Acoustics' proposals, an architectural tender has been launched, with the stage acoustics improvements due to be carried out in 2024.
