摘要： Two or more soundproof cells arranged in a two-dimensional manner are provided. At least one of the soundproof cells is a first soundproof cell configured to include a first frame having a first through-hole. At least one of the other soundproof cells is a second soundproof cell including a second frame having a second through-hole and a film fixed to the second frame. A first shielding peak frequency, which is determined by the first through-hole of the first soundproof cell and at which a transmission loss is maximized, is present on a lower frequency side than a first natural vibration frequency of the film of the second soundproof cell, and sound in a predetermined frequency band centered on the first shielding peak frequency is selectively insulated.

摘要： There are provided a soundproof structure and an opening structure capable of suppressing degradation of sound absorbing characteristics due to resonance vibration. A micro perforated plate having a plurality of through-holes passing therethrough in the thickness direction and a first frame body, which is disposed in contact with one surface of the micro perforated plate and has a plurality of hole portions, are provided. The opening diameter of the hole portion of the first frame body is larger than the opening diameter of the through-hole of the micro perforated plate. The opening ratio of the hole portion of the first frame body is larger than the opening ratio of the through-hole of the micro perforated plate. The resonance frequency of the micro perforated plate in contact with the first frame body is higher than the audible range.
