SOUNDPROOF WALL AND SOUND ABSORPTION PANEL
To provide a soundproof wall facility capable of obtaining a sufficient soundproof effect even in a portion where a region in the vertical direction is high, and a sound absorption panel.SOLUTION: A sound insulating panel 1A is provided with a first outer frame body 5A in which a first sound absorption material 3A is internally mounted, a sound transparent surface provided with numerous sound introducing holes 6 being formed on a sound source side surface part of the first outer frame body 5A, and a sound insulating surface on the back side is arranged at multiple stages in the vertical direction. A sound absorption panel 1B provided with a second outer frame body 5B in which a second sound absorption material 3B is internally mounted, and a sound transparent surface provided with numerous sound introducing holes 6 being formed on the sound source side surface part of the second outer frame body 5B and the back side is further arranged on the uppermost stage of the sound insulating panel 1A arranged at multiple stages in the vertical direction. In the second sound absorption material 3B, multiple sheets of sound absorption plates 30 along the vertical direction are arranged in the panel thickness direction with a space.SELECTED DRAWING: Figure 2
【課題】上下方向の領域の高い部分でも十分な防音効果を得ることのできる防音壁設備及び吸音パネルを提供する。【解決手段】 第１吸音材３Ａを内装した第１外枠体５Ａを設け、音導入孔６を多数設けてある音透過面を第１外枠体５Ａの音源側表面部に形成してあると共に、背面部には遮音面を備えてある遮音パネル１Ａを、上下方向に複数段に並べ、第２吸音材３Ｂを内装した第２外枠体５Ｂを設け、音導入孔６を多数設けてある音透過面を、第２外枠体５Ｂの音源側表面部及び、背面部に形成してある吸音パネル１Ｂを、上下方向に複数段に並べてある遮音パネル１Ａの内の最上段の物の更に上に配設し、第２吸音材３Ｂは、上下方向に沿った複数枚の吸音板３０を、パネル厚み方向に互いに間隔を空けて並設してある。【選択図】図２
