SOUND INSULATION BARRIER

To provide a sound insulation barrier having a sound absorbing panel at an upper end, in which a sound absorbing material such as polyester wool is not arranged in an internal space.SOLUTION: A sound insulation barrier 100 includes: a body wall 1 erected so as to partition a sound source side and a sound receiving side; and a sound absorbing panel 2 installed at an upper end of the body wall 1. The sound absorbing panel 2 includes: a first perforated plate 3 on the sound source side provided with a large number of through holes 3a; a second perforated plate 4 on the sound receiving side provided with a large number of through holes 4a; and an upper frame 5 connecting an upper end of the first perforated plate 3 and an upper end of the second perforated plate 4. A space between the perforated plates 3, 4 facing each other in a direction connecting the sound source side and the sound receiving side is hollow.SELECTED DRAWING: Figure 1A 【課題】ポリエステルウールなどの吸音材が内部空間に配置されていない吸音パネルを上端部に有する防音壁を提供すること。【解決手段】音源側と受音側とを仕切るように立設される本体壁１と、本体壁１の上端に設置される吸音パネル２と、を備える防音壁１００である。吸音パネル２は、多数の貫通孔３ａが設けられた音源側の第１多孔板３と、多数の貫通孔４ａが設けられた受音側の第２多孔板４と、第１多孔板３の上端と第２多孔板４の上端とを接続する上枠５と、を有し、音源側と受音側とを結ぶ方向で対向する多孔板３、４同士の間が中空とされている。【選択図】図１Ａ
