Soundproof structure and sound absorption panel
The present invention addresses the problem of providing a soundproof structure and a sound absorption panel that achieve high soundproof performance over a wide frequency band and can be downsized and can be used in various environments. The soundproof structure has three or more sheet members each having a plurality of through holes that penetrate the sheet member in the thickness direction, wherein the average opening diameter of the through holes is 1-250 Mu m, the three or more sheet members are layered in the thickness direction so as to be spaced apart from each other, and the distancebetween the adjacent sheet members is 0.1-10 mm.
本发明的课题在于提供一种在宽频带得到高隔音性能，能够小型化，且能够在各种环境中利用的隔音结构体及吸音面板。具有3张以上的板部件，该板部件具有沿厚度方向贯穿的多个贯穿孔，贯穿孔的平均开口直径为1μm以上且250μm以下，3张以上的板部件沿厚度方向隔开间隔而层叠，相邻的板部件之间的距离为0.1mm以上且10mm以下。
