Abstract
Measurements were made in a 1:10 scale model of a 1500-seat multi-purpose hall to investigate the acoustic properties of its opera mode. The length from the stage front to the rear wall is 33 m and its maximum width is 28 m with a volume of 14300 m3. Reflecting surfaces were included to scatter early energy from the stage area onto the audience areas. Several settings of the sources were used on the platform and in the pit in order to determine how a lack of brilliance caused by diffraction occurred in the stalls audience. The advantages of the curved ceiling surface in front of the proscenium above the orchestra pit were exploited. In addition, the effect of some diffusing treatments on surfaces adjacent to the pit and on the side walls was also investigated.
