SOUNDPROOF STRUCTURE AND SOUNDPROOF STRUCTURE MANUFACTURING METHOD
A soundproof structure has a plurality of soundproof cells arranged in a two-dimensional manner. Each of the plurality of soundproof cells includes a frame formed of a frame member forming an opening and a film fixed to the frame. Two or more types of soundproof cells having different first resonance frequencies are present in the plurality of soundproof cells. A shielding peak frequency at which transmission loss is maximized is present within a range equal to or higher than a lowest frequency among first resonance frequencies of the soundproof cells and equal to or lower than a highest frequency among the first resonance frequencies of the soundproof cells.
