Use resonance sound absorbing structure's sound barrier cell board

The utility model belongs to the technical field of the noise abatement, especially, relate to an use resonance sound absorbing structure's sound barrier cell board. It includes front panel, rear panel, its characterized in that, the front panel on be provided with the perforation, according to noise source frequency distribution characteristic design aperture and percent opening, reach the purpose of eliminating specific frequency band sound wave, be provided with porous sound -absorbing material in the middle cavity of front panel and rear panel, can be through the resonance principle noisemuting that disappears, adopt concave -convex type socket -spigot connection between the sound barrier cell board for the loaded down with trivial details equipment mode of sound barrier becomes simple swift. 本实用新型属于噪音治理技术领域，尤其涉及种应用共振吸声结构的声屏障单元板。其包括前面板、后面板，其特征在于，所述的前面板上设置有穿孔，根据噪声源频率分布特性设计孔径及开孔率，达到消除特定频带声波的目的；所述前面板和后面板的中间空腔内设置有多孔吸声材料，能够通过共振原理消除噪音；声屏障单元板之间采用凹凸型承插式连接，使得声屏障繁琐的组装方式变得简单快捷。
