The invention provides a microporous metal sound absorber which comprises a shell and a silencing lining piece located in the shell, the shell comprises a face plate, a back plate, an upper side plate and a lower side plate, the upper side plate and the lower side plate are connected with the face plate and the back plate at the same time, the silencing lining piece is arranged between the upper side plate and the lower side plate, the silencing lining piece comprises a microporous plate set, and the microporous plate set is arranged between the upper side plate and the lower side plate. The microporous plate group comprises at least two microporous plates, each microporous plate is formed by splicing two or more microporous plate sections, the distance between the two microporous plates is 20-60mm, and two ends of each microporous plate are embedded between the upper side plate and the lower side plate. The sound absorption lining piece in the sound barrier is designed, the double-layer micro-pore plate is adopted, the service life of the sound absorption lining piece is effectively prolonged, environmental pollution and harm to human bodies are reduced, the micro-pore plate in the sound absorption lining piece is designed in a sectional type assembly mode, the sound absorption performance of the sound absorption lining piece is effectively improved, and the sound absorption lining piece has wide market application value.
本发明提供一种微孔金属吸声体，其包括外壳和位于所述外壳内的消声衬件，所述外壳包括面板、背板和同时连接所述面板和背板的上侧板和下侧板，所述消声衬件设置在所述上侧板和下侧板之间，所述消声衬件包括微孔板组，所述微孔板组包括至少两个微孔板，所述微孔板由两个或以上的微孔板段拼接组成，所述两微孔板之间的距离为20~60mm，所述微孔板的两端嵌设在所述上侧板和下侧板之间。其通过对声屏障内部的吸声衬件进行设计，采用双层微孔板，有效延长了吸声衬件的使用寿命，减少了环境污染和对人体的伤害，本吸声衬件中的微孔板采用分段式组装设计，有效提高了其吸声性能，具备广阔的市场应用价值。
