吊顶吸音板详细介绍：由于体育馆的空间较大，声音发出后会在馆内通过体育馆内的墙壁和天花板形成混响回音，故需进行噪音控制。为了使体育馆内混响回音降低，除墙面采用吸声材料墙面外，在体育馆吊顶安装空间吸声体，将其悬挂于空中，吸声体各个侧面都能与声波接触，起到空间吸声的作用。空间吸声体具有吸声效果好、整洁美观、吸声参数（吸声参数/频率Hz）满足吸声要求的优质产品，且吸声体的尺寸、厚度应满足设计要求。体育馆空间吸声体一般使用1200mm长600mm宽的规格长条状空间吸声体。
吊顶吸音板的性能要求：吸声系数实测频率特性应不小于以下值（混响室法）；空间吸声体应到达防火性能B1级；在20摄氏度室温下，65%相对湿度条件下，回潮率≤0.8%。400mm厚及75mm厚的吸声体的单位面积重量应≤8kg/m2。具有环保性、防污、防尘、可擦洗，***无超标挥发物，质量符合国家有关环保标准或规定。常规规格：1200*600*50 1200*800*50 2400*1200*50 800*800*50 600*600*25 600*600*50。
吊顶吸音板安装：1、定位：主要是悬挂件的定位，而悬挂件定位要根据每榀桁架上弦节点的距离***量取确定，然后划线标记；2、悬挂件焊接：根据已标记好的悬挂件位置，将悬挂件焊接于檀条下方。注意排列整齐、焊接牢固。3、吸声体安装：吸声体安装在悬挂件安装焊接就位后，用U型环悬挂，马道上的吸声体用铁丝绑扎，要求排列有规律，与水平面垂直，整体美观。吸声体安装时要防止尖锐器具刺破，影响吸音及美观效果。
吊顶吸音板用于需做音质设计的各种高、中级装修场所：宾馆酒楼、办公室、影院、剧院、体育馆、录音室、演播厅、会议厅、歌舞厅、健身房、交易所、营业厅、卡拉OK厅、保龄球馆、语音室、排练厅、医院、图书馆、车站候车室、餐厅、试听室、家庭影院等。
Ceiling sound absorbing board details: because the stadium space is large, the sound will be issued in the stadium through the stadium wall and ceiling reverberation echo, so the need for noise control. In order to make the stadium reverberation echo is reduced, in addition to the wall using sound-absorbing material in the stadium wall, ceiling installation space absorber, the hanging in the air, absorbing body each side can play space and acoustic contact, the effect of sound absorption. The space absorber has good sound absorption effect, neat and beautiful, and the sound absorption parameter (sound absorption parameter / frequency Hz) meets the requirements of sound absorption, and the size and thickness of the absorber should meet the design requirements. 1200mm sound absorber with long 600mm width is widely used in the space sound absorber of gymnasium.
Performance requirements of ceiling sound-absorbing panels: the frequency characteristics of sound absorption coefficient measurement should be not less than the following values (reverberation); space absorber should reach B1 grade fireproof performance; room temperature at 20 degrees Celsius, 65% relative humidity, moisture content is less than or equal to 0.8%. The thickness of 400mm and thickness of 75mm absorption body weight per unit area should be less than 8kg/m2. It has environmental protection, antifouling, dustproof, scrub, non-toxic, no excessive volatile, the quality is in line with the relevant national environmental standards or regulations. Conventional specifications: 1200*600*50 1200*800*50 2400*1200*50 800*800*50 600*600*25 600*600*50.
The ceiling panels installed: 1, location: mainly positioning suspension, and the suspension position according to the distance of the exact amount of each truss chord node set, and then marking; 2, suspension parts: welding according to the labeled good suspension position, will be suspension parts welded to the purlin below. Pay attention to neat arrangement and firm welding. 3, installation: absorber absorber installed in suspension installation welding in place, with U ring hanging wire lashing absorber on road, arranged regularly, vertical and horizontal plane, the overall appearance. When the sound absorber is installed, it is necessary to prevent the sharp instrument from piercing and affect sound absorption and aesthetic effect.
The ceiling sound-absorbing panels to be used in the design of all kinds of high quality, intermediate decorate place: Hotel, office, cinema, theatre, gymnasium, recording studio, studio, conference hall, dance hall, gymnasium, exchange, business hall, Kara OK hall, bowling alley, speech room, rehearsal hall, library, hospital, station the waiting room, dining room, audition room, home theater etc..
