Title (EN) SOUND ABSORBING MATERIAL
(FR) MATÉRIAU ISOPHONIQUE
(JA) 吸音材
Abstract:
(EN) Sound absorbing material provided with a fiber group formed from inorganic fibers, organic fibers or a combination of these fibers, wherein at least points of bonding between fibers in the fiber group are coated with a polymer coating film having a loss coefficient of 0.1 or greater.
(FR) L'invention concerne un matériau isophonique pourvu d'un groupe de fibres formé à partir de fibres inorganiques, de fibres organiques ou d'une combinaison de ces fibres, au moins des points de liaison entre les fibres dans le groupe de fibres étant revêtus d'un film de revêtement polymère ayant un coefficient de perte supérieur ou égal à 0,1.
(JA) 無機繊維、有機繊維またはこれらの混合繊維からなる繊維群を備えた吸音材であって、前記繊維群における少なくとも繊維間の結合点が0.1以上の損失係数を有するポリマーコート膜で被覆されている吸音材である。
