SOUND INSULATION SHEET AND SOUND INSULATION STRUCTURE
To provide a sound insulation sheet having excellent sound insulation performance in a low frequency band and having a compact structure.SOLUTION: A sound insulation sheet 1 includes a concavo-convex structure 3 in which a plurality of concavo-convex unit shapes 4 each including a convexity 5 and a concavity 6 is arranged on one surface 2a of a sheet-like base material 2 having a longitudinal direction and a shorter direction as seen in plan view. By linearly arranging a plurality of convexities 5 in the longitudinal direction of the base material 2, sound insulation performance in a low frequency band is improved.SELECTED DRAWING: Figure 1
【課題】低周波数帯の遮音性能に優れ、コンパクトな構成の遮音シートを提供する。【解決手段】平面視で長手方向と短手方向を有する形状のシート状の基材２の一方の面２ａに、凸部５と凹部６からなる凹凸単位形状４を複数配置して構成された凹凸構造３を設けて遮音シート１を形成する。凸部５を基材２の長手方向に沿って線状に複数配置することで低周波数帯域の遮音性能を向上させる。【選択図】図１
