Lothar Cremer in Spain: his influence on the Architect García de Paredes

摘要

This paper presents the most relevant conclusions about the influence of the German consultant Lothar Cremer on the Spanish Architect José María García de Paredes. Within the production of García de Paredes, auditoriums constitute a proper board of singular importance as he has designed and built more than a dozen of large auditoriums, highlighting Auditorio Nacional de Musica (Madrid, 1988). García de Paredes was in touch with Lothar Cremer, who collaborated as an Acoustical Consultant in Auditorio Manuel de Falla (Granada, 1978) and Auditorio Nacional de Música, but his influence extends to other halls such as Sala Juan de Villanueva (Madrid, 1983) and Palau de la Música (Valencia, 1987). Cremer's advice is expressed in the treatment of geometrical acoustics (study of reflections from ceilings, walls and balustrades of balconies to determine their own orientation), distribution of public, slope of the stands and choice of materials. The Architect's contact with the Acoustic Consultant is essential to understand the final outcome of these works, which will be demonstrated by analyzing the project evolution until the final construction of the auditoriums. Cremer´s advice and some images of the optical models are unpublished material.
