Soundproof structure and sound absorbing panel |
| abstract |
An object of the present invention is to provide a soundproof structure and a sound absorbing panel that can obtain high soundproofing performance in a wide frequency band, can be miniaturized, and can be used in various environments. It has three or more sheet members having a plurality of through holes penetrating in the thickness direction, the average opening diameter of the through holes is 1 μm or more and 250 μm or less, and three or more sheet members are laminated apart from each other in the thickness direction. The distance between adjacent sheet members is 0.1 mm or more and 10 mm or less. |
