一般在100平米左右的小型会议厅,如果房间内有地毯、窗帘、沙发等吸音效果好的材料,一般不需要做额外的吸音处理。对于200平方米以上的会议厅,通常需要附加吸音系统。舞台音响设备中的吸音材料分为;
Generally, for small conference halls with an area of about 100 square meters, if there are carpets, curtains, sofas and other materials with good sound-absorbing effect in the room, there is generally no need to do additional sound-absorbing treatment. For conference halls over 200 square meters, additional sound-absorbing systems are usually required. The sound-absorbing materials in stage audio equipment are divided into:;
过从表面到内部的许多细小开口通道来衰减声波的多孔材料,主要吸收中高频声波,以及各种纤维状聚集体结构。有机或无机纤维及其制品,以及多孔结构的开孔泡沫塑料和膨胀珍珠岩制品。
Porous materials that attenuate sound waves through many small open channels from the surface to the interior, mainly absorb medium and high frequency sound waves and various fibrous aggregate structures. Organic or inorganic fibers and their products, as well as porous foamed plastics and expanded perlite products.
通过共振吸收声音的柔性材料(如闭孔泡沫,吸收中频),薄膜材料(如塑料薄膜或布,帆布,油毡和人造革,吸收低频和中频),板材(如如胶合板、硬纸板、石棉水泥板和石膏板,吸收低频)和穿孔板(在各种板材或金属板上打孔制成,吸收中频)。
Flexible materials that absorb sound through resonance (such as closed cell foam, absorbing medium frequency), film materials (such as plastic film or cloth, canvas, linoleum and artificial leather, absorbing low frequency and medium frequency), plates (such as plywood, cardboard, asbestos cement board and gypsum board, absorbing low frequency) and perforated plates (made by punching holes in various plates or metal plates, absorbing medium frequency).

上述材料的复合使用,可以扩大吸声范围,提高吸声系数。贴在墙壁或天花板上的装饰性吸音板,与安装在墙壁上的多孔材料和穿孔板或膜材料相结合,甚至是云状悬挂,可以改善室内音质和控制噪音。除了吸收空气声之外,多孔材料还可以衰减固体声和空气声引起的振动。
The composite use of the above materials can expand the sound absorption range and improve the sound absorption coefficient. The decorative sound-absorbing board attached to the wall or ceiling, combined with porous materials and perforated board or membrane materials installed on the wall, or even cloud suspension, can improve indoor sound quality and control noise. In addition to absorbing air sound, porous materials can also attenuate the vibration caused by solid sound and air sound.
将多孔材料填充到由各种板状材料组成的复合结构中,可以提高隔声能力,减轻结构重量。一种吸收入射声能的材料。吸音材料主要用于控制和调节房间内的混响时间。
Filling porous materials into the composite structure composed of various plate materials can improve the sound insulation ability and reduce the weight of the structure. A material that absorbs incident sound energy. Sound absorbing materials are mainly used to control and adjust the reverberation time in the room.
吸音材料消除回声,改善室内聆听条件;用于在嘈杂场所降低噪音,改善生活环境和工作条件(见吸音降噪);也广泛用于降低通风和空调管道的噪音。根据其物理性质和吸声方式,吸声材料可分为多孔吸声材料和共振吸声结构两大类。后者包括单谐振器、穿孔板谐振吸声结构、薄板吸声结构和柔顺材料等。
Sound absorbing materials eliminate echoes and improve indoor listening conditions; It is used to reduce noise in noisy places and improve living environment and working conditions (see sound absorption and noise reduction); It is also widely used to reduce the noise of ventilation and air conditioning pipes. According to their physical properties and sound absorption methods, sound-absorbing materials can be divided into porous sound-absorbing materials and resonant sound-absorbing structures. The latter includes single resonator, perforated plate resonant sound-absorbing structure, thin plate sound-absorbing structure and compliant material.
山东舞台灯光音响厂家在此提醒大家,在选择吸音材料时,要从吸音性能的角度来确定符合要求的材料,同时还要考虑防火的要求。建筑物的防潮、防潮、防蛀、强度、外观、室内装饰等应结合起来进行考虑选择。更多相关内容的了解就来网站www.wenguangzhineng.com咨询吧!
Shandong stage lighting and sound manufacturers remind you that when selecting sound-absorbing materials, we should determine the materials that meet the requirements from the perspective of sound-absorbing performance, and also consider the requirements of fire prevention. The dampproof, dampproof, moth proof, strength, appearance and interior decoration of buildings shall be considered and selected together.
