The invention provides a sound-absorbing wallboard which has a remarkable sound insulation effect on low-frequency noise and medium-high-frequency noise. The sound-absorbing wallboard comprises a keel component and a sound-absorbing component, a first outer layer plate; a second outer layer plate; a plurality of first sound absorption holes are formed in the surface of the first sound absorption plate, the first sound absorption holes are blind holes, and the openings of the first sound absorption holes face the first outer layer plate; a plurality of second sound-absorbing holes are formed in the surface of the second sound-absorbing plate, the second sound-absorbing holes are blind holes, and openings of the second sound-absorbing holes face the second outer-layer plate; wherein a first damping fin is arranged on the surface, opposite to the surface provided with the first sound absorption holes, of the first sound absorption plate, and a second damping fin is arranged on the surface, opposite to the surface provided with the second sound absorption holes, of the second sound absorption plate. By means of the optimized internal structure, gathering and dissipation of wide-frequency-band sound waves are achieved, and a remarkable sound insulation effect on low-frequency noise and medium-high-frequency noise is achieved.
本发明提供一种对于低频噪音和中高频噪音均有显著隔声效果的吸音墙板。一种吸音墙板，包括：龙骨部件；第一外层板；第二外层板；第一吸音板，所述第一吸音板表面设有若干第一吸音孔，所述第一吸音孔为盲孔，第一吸音孔的孔口朝向于第一外层板；第二吸音板，第二吸音板表面设有若干第二吸音孔，第二吸音孔为盲孔，第二吸音孔的孔口朝向于第二外层板；其中，第一吸音板在与设置有第一吸音孔相对的表面设有第一阻尼片，第二吸音板在与设置有第二吸音孔相对的表面设有第二阻尼片。本发明通过优化的内部的结构实现对于宽频段声波的聚集和消散，对于低频噪音和中高频噪音均有显著的隔声效果。
