Composite damping light sound insulation wall
The composite damping light sound insulation wall comprises a light sound insulation layer, composite damping layers and a sound absorption matching layer, the composite damping layers are arranged on the two sides of the sound absorption matching layer correspondingly to form a sandwich structure, and the light sound insulation layer is arranged on the outer surface of the composite damping layers; the composite damping layer comprises damping layers, shearing columns and air layers, the damping layers are arranged at the two ends of the shearing columns respectively, the shearing columns are periodically distributed along the damping layers, and the air layers are located between the adjacent damping layers; the sound absorption matching layer is composed of a porous sound absorption material, a Helmholtz resonance cavity and light steel keels, the light steel keels are arranged on the two sides of the porous sound absorption material respectively, and the Helmholtz resonance cavity is obliquely embedded in the porous sound absorption material. The light sound insulation wall is small in thickness, light in weight and small in surface density, meets the requirements of modern buildings for light materials, is excellent in performance in a low-frequency range, has a wide sound insulation frequency band, can effectively isolate low-frequency sound waves and reduce propagation and reflection of the sound waves, and is excellent in sound insulation performance.
本发明公开了一种复合阻尼轻质隔声墙，包括轻质隔声层、复合阻尼层和吸声匹配层，复合阻尼层分别设置于吸声匹配层的两侧，形成夹心结构，轻质隔声层设置于复合阻尼层的外表面；复合阻尼层包括阻尼层、剪切柱和空气层，阻尼层分别设置于剪切柱的两端，剪切柱沿着阻尼层周期性分布，空气层位于相邻阻尼层之间；吸声匹配层由多孔吸声材料、赫姆霍兹共鸣腔和轻钢龙骨组成，轻钢龙骨分别设置于多孔吸声材料的两侧，赫姆霍兹共鸣腔倾斜内嵌于多孔吸声材料的内部。本发明厚度薄、质量轻、面密度小，满足现代建筑对轻质材料的需求，轻质隔声墙在低频范围内表现出色，具有较宽的隔声频带，能有效隔离低频声波，减少声波的传播和反射，隔声性能优异。
