一般在100平米左右的小型會議廳，如果房間內有地毯、窗簾、沙發等吸音效果好的材料，一般不需要做額外的吸音處理。對于200以上的會議廳，通常需要附加吸音系統。舞臺音響設備中的吸音材料分為;
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:;
過從表面到內部的許多細小開口通道來衰減聲波的多孔材料，主要吸收中高頻聲波，以及各種纖維狀聚集體結構。有機或無機纖維及其制品，以及多孔結構的開孔泡沫塑料和膨脹珍珠巖制品。
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.
通過共振吸收聲音的柔性材料（如閉孔泡沫，吸收中頻），薄膜材料（如塑料薄膜或布，帆布，油氈和人造革，吸收低頻和中頻），板材（如如膠合板、硬紙板、石棉水泥板和石膏板，吸收低頻）和穿孔板（在各種板材或金屬板上打孔制成，吸收中頻）。
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).
上述材料的復合使用，可以擴大吸聲范圍，提高吸聲系數。貼在墻壁或天花板上的裝飾性吸音板，與安裝在墻壁上的多孔材料和穿孔板或膜材料相結合，甚是云狀懸掛，可以改善室內音質和控制噪音。除了吸收空氣聲之外，多孔材料還可以衰減固體聲和空氣聲引起的振動。
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.
將多孔材料填充到由各種板狀材料組成的復合結構中，可以提高隔聲能力，減輕結構重量。一種吸收入射聲能的材料。吸音材料主要用于控制和調節房間內的混響時間。
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.
吸音材料回聲，改善室內聆聽條件；用于在嘈雜場所降低噪音，改善生活環境和工作條件（見吸音降噪）；也廣泛用于降低通風和空調管道的噪音。根據其物理性質和吸聲方式，吸聲材料可分為多孔吸聲材料和共振吸聲結構兩大類。后者包括單諧振器、穿孔板諧振吸聲結構、薄板吸聲結構和柔順材料等。
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.
山東舞臺燈光音響廠家在此提醒大家，在選擇吸音材料時，要從吸音性能的角度來確定符合要求的材料，同時還要考慮防火的要求。建筑物的防潮、防潮、防蛀、強度、外觀、室內裝飾等應結合起來進行考慮選擇。更多相關內容的了解就來網站
