The proscenium frames the performers, and its geometry and detailing affect the perceived scale of the performers, in both acoustical and visual domains.
For the Four Seasons Centre, Sound Space Design made the proscenium arch 2m deep and shaped it to project the sound of the singers. The adjacent balcony fronts work with the arch to assist the projection of both voice and orchestra.
The illustration is generated from our acoustical computer model. It maps the intensity of reflected sound energy from the surfaces around the proscenium. The warm halo of colour around the proscenium is audible as a strong, clear, exciting sound, allowing the performers to sing very quietly and still be heard. SSD took advantage of the depth to hide the loudspeakers used for announcements and for sound effects.
