SOUNDPROOF WALL FACILITY
PROBLEM TO BE SOLVED: To provide a soundproof wall facility that facilitates improvement of a soundproof effect in a low-frequency sound region.SOLUTION: A soundproof panel 1A, having a rear surface opposite a sound source formed as a sound insulation surface, is lined up in a plurality of tiers in a vertical direction. An outer frame body is provided further above the soundproof panel on a top tier among the soundproof panels lined up in the plurality of tiers in the vertical direction, the outer frame body having a sound absorption space with an interior sound absorption material formed inside, and allowing a partition wall to be formed freely to partition between the sound source and a surrounding. A sound absorption panel 1B is fitted that has a sound permeable surface with a plurality of sound penetrating holes that enable sound input and output between the sound absorption space and the outside formed on a surface of the outer frame body on the sound source side and a rear surface part. The sound absorption material is homogeneous in the vertical direction, and a plurality of sound absorption panels 1B are laminated and fixed with a front surface thereof facing a same way in the vertical direction.SELECTED DRAWING: Figure 1
【課題】低周波音域における防音効果が上げられやすくなる防音壁設備を提供する。【解決手段】音源側とは反対の背面が遮音面に形成してある防音パネル１Ａを、上下方向に複数段に並べ、その上下方向に複数段に並べてある防音パネルの内の最上段の物の更に上に、吸音材を内装した吸音空間を内部に形成すると共に、音源とその音源の周囲とを隔てる隔壁を形成自在な外枠体を設け、吸音空間とその外方とに亘る音の出入りを可能にする音挿通孔を多数設けてある音透過面を、外枠体の音源側表面部、及び、背面部に形成した吸音パネル１Ｂを取り付けて、吸音材は上下均質なものから成り、吸音パネル１Ｂの複数枚を、それらの表面部が上下方向に沿った状態で積み上げて固定してある。【選択図】図１
