房间尺寸确定之后就考虑吸声处理,要做好这个工作,必须掌握不同材料的吸声性能。按照材料的吸声机理,吸声材料可分为两大类:多孔吸声材料和共振吸声材料。多孔材料内部有许多孔隙。检验它的最简单办法是在材料表面吹一吹,透气的就是多孔材料。玻璃棉、矿棉、木丝板、微孔吸声砖、纤维性织物和一般的泡沫塑料等都属于这一类 After determining the size of the room to absorb the sound, to do this work, we must master the sound absorption properties of different materials. In accordance with the sound absorption mechanism of materials, sound absorption materials can be divided into two categories: porous sound-absorbing materials and resonant sound-absorbing materials. Porous materials have many pores inside. The easiest way to test it is to blow on the surface of the material, which is porous material. Glass wool, mineral wool, wood board, microporous sound-absorbing brick, fibrous fabrics and general foam belong to this category
