Silencing structure for building
The invention belongs to the field of sound absorption materials, and particularly relates to a silencing structure for a building, which comprises a metamaterial sound absorber and a porous material layer, the porous material layer is attached to the surface of the metamaterial sound absorber; the metamaterial sound absorber is formed by splicing a plurality of sound absorber units in parallel, each sound absorber unit is provided with an open pore on one side of the porous material layer, and the sound absorber unit is attached to the porous material layer to form a closed cavity with the interior communicated with the open pore; the sound absorption frequency of the metamaterial sound absorber ranges from 300 Hz to 1200 Hz. Full-frequency-band sound absorption is achieved through coupling of the two materials, and the sound absorption frequency band finally used for a silencing structure of a building ranges from 300 Hz to 10000 Hz.
本发明属于吸声材料领域，具体涉及一种用于建筑物的消声构造，包括超材料吸声体和多孔材料层；多孔材料层贴合在超材料吸声体的表面；超材料吸声体由若干吸声体单元并联拼接而成，且每个吸声体单元在多孔材料层的一侧均具有开孔，且和多孔材料层贴合形成内部与开孔联通的封闭腔体；所述超材料吸声体的吸声频率为300‑1200Hz。本发明通过两种材料耦合实现全频带吸声，最终使用于建筑物的消声构造的吸声频带为300‑10000Hz。
