摘要
根据影院的建筑结构,为了满足室内的吸声降噪效果,在影院观众厅四周墙体均采用了新型吸音材料,50厚48kg/m3的进口玻璃棉,进口透声装饰布背面喷防火涂料,V形专用PVC新型龙骨,中间设置空腔。地面采用塑胶地板及地毯铺设,通过采用吸音板与空腔吸声体进行不同组合设置,从而吸收了影院内的高、中、低频声音,保证了影院内声音播放的清晰度。
According to the architecture of cinemas and in order to achieve indoor noise reduction by absorption, new acoustic materials, such as imported glass wool （50 thick, 48kg/m^3）, imported acoustic upholstery fabrics with fire retardant coating on backs, and V-mode dedicated New PVC framing with cavity inside, are applied to four wails of the audience hall. As for the floor, plastic floor boards and carpet are applied. Acoustic boards and hollow sound absorbers are combined and mounted to absorb high/medium/low-frequency sound inside the cinema, ensuring the sound articulation inside.
