文化广场是一座可容12500人的特大型观众厅。平面呈扇形,面积7800米~2,总体积达122,000米~3。这里经常举行文艺演出,也供集会之用。大厅的吸声处理采用了大片“浮云”式吸声平顶,使混响时间控制在2秒左右(500—1000赫),达到了满意的演出效果。大厅的扩声系统采用了半集中式布置的声柱,保证了良好的语言清晰度,并使全场声音分布均匀。
Cultural Square is a large audience hall that can accommodate 12,500 people. The plane is fan-shaped, with an area of 7800 meters~2 and a total volume of 122,000 meters~3. Theatrical performances are often held here as well as for meetings. The sound-absorbing treatment of the hall adopts a large piece of “cloud” sound-absorbing flat top, so that the reverberation time is controlled at about 2 seconds (500-1000 Hz), and a satisfactory performance effect is achieved. The lobby’s sound reinforcement system uses a semi-centralized sound column to ensure good speech intelligibility and even sound distribution throughout the entire hall.
