NOISE REDUCTION STRUCTURE
To provide a noise reduction structure capable of reducing noise in both inside and outside of a building.SOLUTION: A noise reduction structure includes a sound absorption mechanism 20 that is provided in at least one of a ceiling surface and a side wall surface of a veranda 12 in a building 10 and absorbs noise from the outside. The sound absorption mechanism 20 includes: a reflection unit 32A that is inclined so as to expand from a window surface toward a tip end of the veranda 12 to reflect noise; and a sound absorption unit 32B that absorbs reflected sound reflected by the reflection unit 32A.SELECTED DRAWING: Figure 1
【課題】建物内外双方の騒音を低減できる騒音低減構造を提供する。【解決手段】騒音低減構造は、建物１０におけるベランダ１２の天井面及び側壁面の少なくとも一方に設けられると共に、外部から入射する騒音を吸音する吸音機構２０を備え、吸音機構２０は、窓面からベランダ１２の先端に向かって拡がるように傾斜して騒音を反射する反射部３２Ａと、反射部３２Ａで反射した反射音を吸音する吸音部３２Ｂと、を備える。【選択図】図１
