Title (EN) SOUND ABSORPTION BODY
(FR) CORPS D'ABSORPTION SONORE
(JA) 吸音体
Abstract:
(EN) This sound absorption body includes a non-woven fabric or a non-woven-fabric stacked body. The non-woven fabric or the non-woven-fabric stacked body comprises fibres having an average fibre diameter of less than 3,000 nm. The thickness of the non-woven fabric or the non-woven-fabric stacked body is less than 10 mm. The flow resistance per unit thickness of the non-woven fabric or the non-woven-fabric stacked body is greater than 4.0E+06 Ns/m4, and lower than 5.0E+08 Ns/m4. The bulk density of the non-woven fabric or the non-woven-fabric stacked body is greater than 70 kg/m3, and less than 750 kg/m3.
(FR) L'invention concerne un corps d'absorption sonore, qui comprend un non-tissé ou un corps empilé de non-tissé. Le non-tissé ou le corps empilé de non-tissé comprend des fibres ayant un diamètre moyen de fibre inférieur à 3 000 nm. L'épaisseur du non-tissé ou du corps empilé de non-tissé est inférieure à 10 mm. La résistance à l'écoulement par unité d'épaisseur du non-tissé ou du corps empilé de non-tissé est supérieure à 4,0E+06 Ns/m4 et inférieure à 5,0E+08 Ns/m4. La densité apparente du non-tissé ou du corps empilé de non-tissé est supérieure à 70 kg/m3 et inférieure à 750 kg/m3.
(JA)  不織布又は不織布の積層体を含む吸音体であって、前記不織布又は不織布の積層体が、平均繊維径が3,000nm未満の繊維からなり、前記不織布又は不織布の積層体の厚さが10mm未満であり、前記不織布又は不織布の積層体の単位厚さ流れ抵抗が4.0E+06Ns/m4より大きく且つ5.0E+08Ns/m4より小さく、及び前記不織布又は不織布の積層体の嵩密度が70kg/m3より大きく且つ750kg/m3より小さい、前記吸音体。
