Soundproofing structure, partition structure, window member, and cage |
| abstract |
The present invention addresses the problem of providing: a soundproofing structure which achieves high soundproofing performance across a wide frequency band, is compact and lightweight, ensures ventilation properties, and transmits light; a partition structure; a window member; and a cage. A soundproofing structure equipped with a plate-shaped member having a plurality of through-holes passing therethrough in the thickness direction, wherein: the average diameter of the opening in the through-holes is no less than 0.1μm and less than 100μm, and given that the average diameter of the opening in the through-holes is phi (μm) and the thickness of the plate-shaped member is t (μm), then the average opening ratio in the through-holes is greater than 0 and less than 1, and falls in a range in which the center of the range is rho_center=(2+0.25×t)×phi -1.6 , the lower limit of the range is rho_center-(0.052×(phi/30) -2 ), and the upper limit of the range is rho_center+(0.795×(phi/30) -2 ). |
