CONTRACTIVE/EXPANSIVE SOUND ABSORBING PANEL
To widely absorb sound from a noise source at a sound absorbing sheet 1 side through passing a sound absorbing sheet 1/an air layer 15 and reflection at a sound insulation sheet 10, and to change a distance between posts 20A, 20B by a contractive/expansive mechanism 50 while keeping the sound absorbing effect.SOLUTION: A sound absorbing sheet 1 and a sound insulation sheet 10 that can be folded are disposed in parallel to each other and are attached to posts 20A, 20B, and a pantograph-shaped contractive/expansive mechanism 50 disposed on an inner face 2 of the sound absorbing sheet 1 and on an inner face 11 of the sound insulation sheet 10 is fixed to the posts 20A, 20B to constitute a contractive/expansive sound absorbing panel 60. Following the contractive/expansive motion of the contractive/expansive mechanism 50, the sound absorbing sheet 1 and the sound insulation sheet 10 are folded without contact of the inner face 2 with the inner face 11. A distance between the posts 20A, 20B can be adjusted in a range of L10 to L20, and an air layer 15 can be always formed between the sound absorbing sheet 1 and the sound insulation sheet 10.SELECTED DRAWING: Figure 2
【課題】吸音シート１側の騒音源からの音を、吸音シート１・空気層１５の通過、遮音シート１０での反射を経て大幅に吸音できる。この吸音効果を維持したまま、伸縮機構５０により支柱２０Ａ、２０Ｂの距離を可変できる。【解決手段】折り畳み可能な吸音シート１、遮音シート１０を並列して配置して支柱２０Ａ、２０Ｂに取り付けし、吸音シート１の内面２、遮音シート１０の内面１１に配置したパンタグラフ状の伸縮機構５０を支柱２０Ａ、２０Ｂに固定して、伸縮吸音パネル６０を構成する。伸縮機構５０の伸縮に追随して、吸音シート１と遮音シート１０が内面２、１１が接触することなく折り畳まれ、支柱２０Ａ、２０Ｂ間の距離をＬ１０～Ｌ２０で調整でき、かつ吸音シート１と遮音シート１０との間に常に空気層１５を形成できる。【選択図】図２
