title THE INFLUENCE OF THE SIMPLIFIED ARCHITECTURAL MODEL ON THE ACOUSTICAL SIMULATION RESULTS
source 17th International Congress on Acoustics, Proceedings : Vol. III - Architectural acoustics - Opera house acoustics - p. 46-47 ISBN : 88-88387-02-1, 2-7 Septembre 2001, Rome, Italy
summary The sometimes complex architectural shape of halls creates modelling difficulties as the simulation computing systems need plane surfaces. In order to approach a perfect shape of curved surfaces, a big number of facets is necessary. This poses, as a consequence, computer memory problems which is the case of the horse shoe shaped Opera House with its richly decorated columns, balconies, etc. This paper compares the acoustical measurement results and the calculation results of a computer simulation software applied on several models (from the most simple till the most complex ones) of the Grand Theatre of Bordeaux.
