SOUND ABSORPTION PANEL AND SOUND ABSORPTION STRUCTURE
To provide a sound absorption panel and sound absorption structure capable of reducing noise from a horizontal direction with a closed space as a sound source generated by the travelling of vehicles.SOLUTION: A sound absorption panel comprises: a plurality of vertically extending reflectors 20 arranged substantially parallel to each other; support members 10 supporting the reflectors 20; and a sound absorption material 30 filling the space between the reflectors 20. The reflectors 20 are inclined in the traveling direction of sound emitted from a sound source 40.SELECTED DRAWING: Figure 1
【課題】車両などの走行に伴って閉鎖空間を音源とする水平方向からの騒音を低減することが可能な吸音パネル及び吸音構造を提供する。【解決手段】互いに略平行に配置された、複数の垂直方向に延伸する反射板２０と、反射板２０を支持する支持部材１０と、反射板２０間の空間を充填する吸音材３０とを備え、反射板２０は、音源４０から発せられる音の進行方向に傾斜している、吸音パネル。【選択図】図１
