SOUNDPROOF STRUCTURE, LOUVER, AND SOUNDPROOF WALL

摘要

Provided is a soundproof structure including at least one soundproof cell having: a frame including a hole section; and a film fixed to the frame so as to cover the hole section, wherein the soundproof cell is disposed at an open member having an opening with the film surface of the film tilted relative to a cross section of the opening of the open member such that the open member has a region serving as a vent that passes gas. Accordingly, a considerable soundproof effect can be exhibited even in a state in which the soundproof cell is attached to the open member with the film surface thereof tilted relative to a sound entering direction, and thus the aperture ratio is high, and noise can be removed and high ventilating properties can be maintained without having to additionally install a duct or cylinder when installing the soundproof cell. Also provided are a louver and a soundproof wall that include the soundproof structure.
