SOUND ABSORBING BODY
To provide a sound absorbing body which exhibits excellent sound-absorption effect in a sound range of daily life noise and has excellent reverberation suppression effect in a low sound range.SOLUTION: A sound absorbing body comprises: sheet-like first and second solid knittings knitted from a pair of base fabrics which are disposed apart from each other and connecting threads connecting the base fabrics by reciprocating between them; and supporting plates which are arranged between the first solid knitting and the second solid knitting and support the first solid knitting and the second solid knitting at a surface and a rear face. The first solid knitting has first permeability and the second solid knitting has second permeability different from the first permeability, and the supporting plates have permeability in at least a plate thickness direction and form air layers between the first solid knitting and the second solid knitting.SELECTED DRAWING: Figure 1
【課題】生活騒音の音域において優れた吸音効果を発揮し、かつ低音域において優れた残響抑制効果を有する吸音体を提供すること。【解決手段】吸音体は、互いに離間して配置された一対の基布と、該基布間を往復して両者を結合する連結糸とから編成されたシート状の第１及び第２の立体編物と、第１の立体編物と第２の立体編物の間に配置され、表裏に第１の立体編物と第２の立体編物をそれぞれ支持する支持板と、を備える。第１の立体編物は、第１の通気度を有し、第２の立体編物は、第１の通気度とは異なる第２の通気度を有し、支持板は、少なくとも板厚方向に通気性を有し、第１の立体編物と第２の立体編物の間に空気層を形成する。【選択図】図１
