PROBLEM TO BE SOLVED: To provide a sound absorption device with large sound absorption effect.SOLUTION: A soundproof wall 10X is constituted so that long parts of a soundproof member 10 which is formed of a reflection cylinder and whose cross section is long polyhedron are continuously connected to be extended in a lateral direction or a horizontal direction, a noise component (a) introduced from a reflection opening 12 is made to interfere on a noise source side of the soundproof member 10 including an inner space in the soundproof member 10, and the sound is absorbed by a sound absorbing member 30 arranged in a position of the reflection opening 12 to efficiently reduce the noise component.SELECTED DRAWING: Figure 2
【課題】吸音効果が大きい吸音装置を提案する。【解決手段】反射筒体でなる長尺な断面多面体でなる防音部材１０を長尺部分が横方向又は縦方向に延長するように、連接させた防音壁１０Ｘを構成し、反射開口１２から導入した騒音成分ａを防音部材１０内の内部空間を含む防音部材１０の騒音源側において干渉させると共に、反射開口１２位置に設けた吸音部材３０によって吸音させることにより、騒音成分を効率よく低減させることができる。【選択図】図２
