SOUND PROOF WALL FACILITY
To provide a sound proof wall facility capable of providing a soundproofing effect different from some conventional measures by providing a new sound reduction device on the sound proof wall.SOLUTION: A sound proof wall facility comprises: a sound proof wall 1A provided with a sound absorbing material 4 inside thereof and a sound insulating surface without any hole; and a sound reduction device 1C provided on a sound source side of the sound proof wall 1A. The sound reduction device 1C has an opening 25 on the sound source side of the sound proof wall 1A and a plurality of blade members spread in the width direction of the sound proof wall 1A at appropriate intervals in the vertical direction. The noise reduction device 1C may further be provided with sheets or panels of an air-permeable material 30 each provided on the tip end side of the blade member so as to cover a groove between the blade members. In addition, a sound absorbing panel which allows sound transmission from the sound source side to the back side and has a sound absorbing material may be provided on the sound proof wall 1A.SELECTED DRAWING: Figure 2
【課題】防音壁に新たな減音装置を設けることで上記従来の施策に別異の防音効果を得ることのできる防音壁設備を提供すること。【解決手段】吸音材４を内装すると共に孔の開いていない遮音面を備える防音壁１Ａと、防音壁１Ａの音源側に設けられた減音装置１Ｃとを備える。この減音装置１Ｃは、防音壁１Ａの音源側に開口２５を有すると共に防音壁１Ａの幅方向に広がる羽根部材を上下方向に適宜間隔を開けて複数設けた。減音装置１Ｃは、羽根部材の先端側にこれら羽根部材の間の溝を覆うように設けられた通気性材料３０のシートまたはパネルをさらに備えてもよい。そして、防音壁１Ａの更に上に音源側から背面側に向かって音の透過を許容し吸音材を有する吸音パネルを設けてもよい。【選択図】図２
