A sound-shielding structure (1) is provided with an elastic membrane section (2), an elastic support wall section (3) provided upright on the membrane section (2), and a weight section (4) provided upright on the membrane section (2). The membrane part (2) is divided into a plurality of partitions (5) by the support wall part (3), the counterweight parts (4) are respectively positioned inside all of the plurality of partitions (5) or inside some of the plurality of partitions (5), and one counterweight part (4) is arranged in one partition (5) in the partitions (5) in which the counterweight parts (4) are positioned. The height (H1) of the support wall section (3) extending in the direction orthogonal to the membrane section (2) is greater than the height (H2) of the weight section (4) extending in the direction orthogonal to the membrane section (2). Each of the weight parts (4) constitutes a spring mass resonator provided with an elastic spring part (4a) and a mass part (4b) having a larger mass than the spring part (4a). The sound-shielding structure (1) can obtain sufficient sound-shielding properties, can be easily and stably placed on a curved-surface-shaped placement surface, and is thin and lightweight. The sound-proof structure (11) comprises a sound-proof plate-shaped part (10) and a sound-proof structure part (9) composed of the sound-proof structure (1), at least one of the film part (2) and the support plate part (3) and the sound-proof plate-shaped part (10) are integrally formed or joined, and the sound-proof plate-shaped part (10) and the sound-proof structure part (9) are arranged side by side on a plane.

    遮音结构体(1)具备具有弹性的膜部(2)、竖立设置于膜部(2)且具有弹性的支撑壁部(3)以及竖立设置于膜部(2)的配重部(4)。膜部(2)被支撑壁部(3)分成多个划区(5),配重部(4)分别位于多个划区(5)的全部的内部或多个划区(5)中的一部分划区(5)的内部,在配重部(4)位于内部的划区(5)中,在一个划区(5)配置一个配重部(4)。支撑壁部(3)的沿与膜部(2)正交的方向延伸的高度(H1)比配重部(4)的沿与膜部(2)正交的方向延伸的高度(H2)大。配重部(4)分别构成具备具有弹性的弹簧部(4a)和比弹簧部(4a)质量大的质量部(4b)的弹簧质量共振器。遮音结构体(1)能够得到充分的遮音性,在曲面状的载置面也能够容易且稳定地载置,且为薄型且轻量。防音结构体(11)包括防音板状部(10)和由遮音结构体(1)构成的遮音构造部(9),膜部(2)以及支撑板部(3)中的至少一方和防音板状部(10)一体形成或者接合,防音板状部(10)和遮音构造部(9)在平面上排列设置。
