SOUNDPROOF STRUCTURE, AND SOUNDPROOF PANEL
To provide a soundproof structure and a soundproof panel which have a relatively small structure and can absorb sound of relatively low frequency in a wide band.SOLUTION: A soundproof structure 10 and a soundproof panel comprise: a core body 12 constituting a plurality of cells 14; a back plate 18 covering opening surfaces of each of a plurality of cells in a thickness direction of the core body; a perforated plate 20 covering the opening surfaces of each of the plurality of cells at positions opposite to the back plate in the thickness direction and having through-holes 22; and a flow resistor 24 overlapped on the perforated plate at a position opposite to the core body in the thickness direction and having air permeability. The flow resistance of the flow resistor is 350 Pa s/m or more and 1,500 Pa s/m or less.SELECTED DRAWING: Figure 1
【課題】比較的小型な構造で、且つ、比較的低周波の音を広帯域で吸音することが可能な防音構造体及び防音パネルを提供する。【解決手段】本発明の防音構造体１０及び防音パネルは、複数のセル１４を構成するコア体１２と、コア体の厚み方向において複数のセルの各々の開口面を覆う背面板１８と、厚み方向において背面板とは反対側の位置で複数のセルの各々の開口面を覆い、且つ、貫通孔２２が形成された有孔板２０と、厚み方向においてコア体とは反対側の位置で有孔板に重ねられ、且つ、通気性を有する流れ抵抗体２４と、を有する。流れ抵抗体の流れ抵抗が、３５０Ｐａ・ｓ／ｍ以上、且つ、１５００Ｐａ・ｓ／ｍ以下である。【選択図】図１
