Cinema playing acoustic building structure
The invention discloses a cinema playing acoustic building structure. The cinema playing acoustic building structure comprises a first side wall and a second side wall, a decoration joint A and a decoration joint B are correspondingly arranged on the first side wall and the second side wall, and the decoration joint A and the decoration joint B are arranged on a first side wall surface structure and a second side wall surface structure in a staggered mode. The arrangement positions of the decoration joint A and the decoration joint B on the first side wall and the second side wall are staggered, the decoration joint A comprises a plastering leveling layer, a cavity layer, a steel wire mesh, superfine glass wool white glass wool cloth, a flame-retardant plate cutting strip and a GCP plate which are sequentially arranged on the surface of the wall body, and the decoration joint B comprises a plastering leveling layer, a cavity layer, a gypsum board and a GPC board which are sequentially arranged on the surface of the wall body. The sound absorption effect of the decoration joint A is high, but audiences feel uncomfortable due to the fact that only the decoration joint A is adopted, the reverberation time is too short, discomfortable auditory sense of audiences can generate, so that the decoration joint B is designed, superfine glass silk floss filling is eliminated, a layer of gypsum board is additionally arranged to improve sound reflection, and the reverberation time is controlled to be optimal.
本发明公开了一种放影院声学建筑构造，包括侧墙一和侧墙二，侧墙一和侧墙二上分别布置有装饰节点A和装饰节点B，装饰节点A和装饰节点B交错布置在侧墙一墙面构造和侧墙二墙面构造上，且侧墙一和侧墙二上的装饰节点A和装饰节点B布置位置存在错位，装饰节点A包括依次设置在墙体表面的抹灰找平层、空腔层、钢丝网、超细玻璃棉包白玻璃丝布、阻燃板裁条和GCP板，装饰节点B包括依次设置在墙体表面的抹灰找平层、空腔层、石膏板和GPC板。装饰节点A的吸声效果较强，但是单纯采用装饰节点A，混响时间过短，会导致观众听觉不适，因此设计了装饰节点B，装修节点二取消超细玻璃丝绵填充，增加一层石膏板提高声音反射，从而控制混响时间达到最佳。
