山东省科技馆国际会议报告厅视听环境设计

The seeing and hearing conditions design of international convention and reporting hall in Shandong province science and technology museum

山东省科技馆国际学术会议报告厅是一座多用途大厅,由原济南剧院观众厅改建而成。在房屋高度低、设计要求高情况下,依据声学、视觉原理,深入分析了各种用途的技术特性、房屋的空间特征,充分利用了现有房屋条件,综合运用建筑设计、装修设计手段进行了报告厅视听环境设计。以要求最严的数字立体声电影厅的混响时间作设计值,注意减弱定向反射声,加强声场扩散处理,吸声材料选用了装饰效果好的阻燃复合吸声板。按照无阻挡视线设计地面,选用投影与电影合用的银幕,将面光桥、扬声器桥设计深入到屋架空间以解决建筑高度不足的问题。使用证明报告厅视听环境优良。

International convention and reporting hall in Shandong province science and technology museum is a multifunction hall. It was rebuild from the original audience hall of Jinan theater. Under the condition of low height and high design demand, by the principle of acoustic and vision, the technology characters and the room characters of the house are gone deep into analyzing. The existing conditions of the building are used completely. The architecture design and fitment design measures are exerted synthetically in the seeing and hearing conditions design. The reverberation time that the figure stereo cinema need most severely is the design value. The directional echo sound is weakened intentionally. The management of sound field diffusion is strengthened. The sound absorption material is the compound sound absorption aboard which has high resistance burning and good ornament effects. The floor is designed according to the principle without obstruction of line of sight. The screen is chosen for both projection and cinema. In order to solve the problem of the lack of the room height, the surface light bridge and the loudhailer bridge are put into the house's shelf room. The following use proved that the seeing and hearing conditions are favorable.
