| titleOfInvention | Soundproof structure and opening structure |
| abstract | The present invention addresses the problem of providing a soundproof structure and an opening structure that are capable of suppressing a reduction in sound absorption characteristics caused by resonance vibration. The present invention is provided with: a micro perforated plate that has a plurality of through-holes penetrating the same in the thickness direction; and a first frame body that has a plurality of holes and that is arranged in contact with one surface of the micro perforated plate, wherein the opening diameters of the holes of the first frame body are larger than those of the through-holes of the micro perforated plate, the opening ratio of the holes of the first frame body is larger than that of the through-holes of the micro perforated plate, and the resonance frequency of the micro perforated plate that comes into contact with the first frame body is higher than the audible range. |
