摘要:
There is provided a laminated soundproof structure formed by laminating a single layer soundproof structure having one or more soundproof cells which are arranged in a two-dimensional plane and each of which includes a frame, a film, and an opening portion including a hole. The single layer soundproof structure has a shielding peak frequency, which is determined by the opening portion of each of the soundproof cells and at which a transmission loss is maximized, on a lower frequency side than a first natural vibration frequency of the film of each of the soundproof cells. The soundproof cells of the single layer soundproof structures are laminated with a distance therebetween, and at least some of the laminated soundproof cells have the same conditions of the frame, the film, and the opening portion.
