SOUNDPROOF STRUCTURE, LOUVER, AND SOUNDPROOF WALL
A soundproof structure has at least one soundproof cell including a frame having a hole portion and a film fixed to the frame so as to cover the hole portion. The soundproof cell is disposed in an opening member having an opening in a state in which a film surface of the film is inclined with respect to an opening cross section of the opening member and a region serving as a ventilation hole, through which gas passes, is provided in the opening member. Therefore, there is provided a soundproof structure in which the film surface of the soundproof cell is attached to the opening member so as to be inclined with respect to the incidence direction of sound so that it is possible to exhibit a large soundproofing effect even in a state of high opening ratio, it is possible to remove noise without additional processing for ducts or pipes at the time of attaching the soundproof cell, and it is possible to maintain high air permeability, and a louver and a soundproof wall having the soundproof structure.
