Sound absorption unit board and totally-closed sound barrier
The invention discloses a sound absorption unit board which comprises a perforating layer, a honeycomb interlayer, a damping layer and a metal layer, wherein the perforating layer, the honeycomb layer, the damping layer and the metal layer are overlapped successively to form a composite board. The honeycomb layer comprises a plurality of honeycomb cores and a porous material layer. The porous material layer is arranged on the peripheral side of the honeycomb cores in a surrounding manner. A plurality of through holes are formed in the perforating layer, the through holes are formed corresponding to the honeycomb cores one by one, and the center axes of the through holes passing the center of circle are superposed with those of the honeycomb cores. The sound absorption unit board has the advantages of being light in self weight, high in strength, better in sound absorption and noise reduction effect and the like.
本发明公开了一种吸声单元板，包括穿孔层、蜂窝夹层、阻尼层和金属层，所述穿孔层、蜂窝夹层、阻尼层和金属层依次叠层布置构成一个复合板；所述蜂窝夹层包括多个蜂窝芯和多孔材料层，所述多孔材料层围设于多个所述蜂窝芯的周侧；所述穿孔层上开设有多个通孔，所述通孔与所述蜂窝芯一一对应布置，所述通孔过圆心的中心轴与所述蜂窝芯的中心轴重叠。本发明具有自重轻、强度高、吸音降噪效果更好等优点。
