SOUND INSULATION SHEET AND SOUND INSULATION STRUCTURE
To provide a sound insulation sheet and a sound insulation structure, which are light, thin and excellent in sound insulation performance of a low frequency band.SOLUTION: A sound insulation sheet 1 includes a concave and convex structure 3 on at least one face of a sheet-like base material 2. The concave and convex structure 3 is formed by providing concave and convex unit shapes 4 formed of convexes 5 protruding in a column shape from a base material surface and concaves 6 around the convexes in array. The convex 5 in each concave and convex unit shape 4 is arranged in a shape so that a root part 51-side is made thinner and a tip part 52-side to be thicker than the root part.SELECTED DRAWING: Figure 1
【課題】軽量且つ薄型で、低周波数帯の遮音性能に優れる遮音シート及び遮音構造体を提供する。【解決手段】シート状の基材２の少なくとも一方の面に凹凸構造３を有する遮音シート１であり、前記凹凸構造３は基材表面から柱状に突出した凸部５とその周囲の凹部６からなる凹凸単位形状４を列設して形成し、各凹凸単位形状４の凸部５を、その根元部５１側を細く、先端部５２側をそれよりも太くした形状に設ける。【選択図】図１
