Resumen
Based on the experience of these two concert halls, this article would like to go beyond their excellent reputation with the public and the musicians to discuss their unresolved issues. The �Philharmonie de Luxembourg� is used mainly for the classic music with a large hall of 1500 seats with a concert pipe organ with 81 stops / 6738 pips (below, left) and a smaller chamber music hall of 304 seats (below, right). The architect Christian de Portzamparc was appointed in 1997 by international competition. This building was inaugurated at July 2005, with much enthusiasm and appreciation, even though there were discrepancies between the results of the calculation, simulation models and the in situ measurements in the occupied hall, for reasons such as the underestimation the low frequency absorption of the audience. The �Sala de Sinfoni� in the Centro Cultural Miguel Delibes of Valladolid has 1 700 seats, and is used mainly for the symphony repertoire (below, left). A chamber music hall of 500 seats (right), a 400 seats experimental theatre and a music conservatory are also included in this huge building. This project was chosen by competition with architect Ricardo Bofill in 2001 and was opened in April 2007. The acoustic need for massive ceiling materials in the halls was contradicted by the requirements. During the construction period, to keep costs down and to ensure seismic safety for the public which is facilitated by lower mass. There was little scientific, quantitative precision on the necessary specific mass. After several concerts, the musicians and audience felt satisfied with the sound´s richness, brilliance and the warmth. The chamber music hall has also a very good reaction from the users, but as yet there is no acoustic measurement of the occupied hall.
