TDS in Scale Models of New Concert Halls
In order to support the acoustical consulting of the newly built concert halls in Paris (Les Halles), The Hague (Netherlands), and Enschede (Netherlands), a scale model technique was applied. 1:16 models were used to study the acoustical conditions in the audience area as well as o the stage. The two-port TDS technique was used (in scale model as well as in real halls), obtaining Energy Time Curves, and using a specially developed omnidirectional sound source. The use of a scale model in the choice between alternatives is illustrated.
