WIPO Patent Application WO/2018/043489
Kind Code:
A1
Abstract:
Provided are a sound-proofing strucuture and a sound-proofing system. The sound-proofing structure comprises two or more sound-proofing units. Each sound-proofing unit comprises a frame having an opening and a sound-proofing material that is mounted to the opening of the frame. Two adjoining sound-proofing units are positioned in such a manner that the sound-proofing materials thereof at least partially face one another, and the sound-proofing materials that at least partially face one another are separated from one another, and the average distance between the sound-proofing materials that at least partially face one another is less than 20 mm. As a result of this configuration it is possible to sound-proof with respect to sound on the low-frequency side with a simple configuration, reduce weight and make the structure more compact, and make it easy to vary the frequency characteristics thereof.
