Abstract
There is provided a soundproof structure that can selectively block sound having a specific frequency emitted from equipment, automobiles, and general households and can change the cutoff frequency of the sound in accordance with a change in the frequency of sound to be blocked. The above problem is solved by providing a laminated film, in which two or more films each including one or more holes drilled therein are laminated, and two rigid frames, which fix the laminated film so as to be interposed from both sides of the laminated film, and making at least parts of the one or more holes in the respective films of the laminated film overlap each other.
