To provide a sound absorption structure capable of obtaining desired sound absorption structure even if a wall face of a wall body is a curve face.SOLUTION: A sound absorption structure 100 comprises: a plurality of resonators 10 which are separately constituted and generate Helmholtz resonance; and a flexible connecting member 20 for connecting the plurality of resonators 10. The resonators 10 are in cylindrical shapes or tubular shapes, openings 15 are formed at first end faces, and second end faces being end faces on opposite sides of the first end faces are bottoms 13. The resonators 10 have flexibility.SELECTED DRAWING: Figure 2

    【課題】壁体の壁面が曲面である場合であっても、所望の吸音効果を得ることが可能な吸音構造体を提供する。【解決手段】吸音構造体100は、互いに別体で構成され、ヘルムホルツ共鳴を生じさせる複数の共鳴器10と、複数の共鳴器10を連結する柔軟な連結部材20と、を有する。共鳴器10は、筒状または管状をなし、第1端面に開口部15が設けられ、第1端面とは反対側の端面である第2端面が底部13である。共鳴器10は、柔軟性を有する。【選択図】図2
