Abstract
(EN)
Provided are: a sound-absorbing material that can absorb sound over a wide range of frequencies from low frequency to high frequency; and a wire harness equipped with said sound-absorbing material. Disclosed is a sound-absorbing material (1) which is a laminated sheet made by laminating base material sheets (3) and a skin material sheet (2) having a smaller basis weight than the base material sheets (3), wherein: the base material sheets (3) include at least a first base material sheet (31) and a second base material sheet (32); and the skin material sheet (2) is arranged between the first base material sheet (31) and the second base material sheet (32). By using said sound-absorbing material (1), a sound-absorber-equipped wire harness (6) is obtained by integrating said sound-absorbing material (1) with a wire harness (7).

L'invention concerne un matériau insonorisant qui peut absorber le son sur une large plage de fréquences depuis les basses fréquences jusqu'aux hautes fréquences ; et un faisceau de câbles équipé dudit matériau insonorisant. Le matériau insonorisant (1) selon l'invention est une feuille laminée réalisée en laminant des feuilles de matériau de base (3) et une feuille de matériau de peau de laminage (2) dont le grammage est inférieur à celui des feuilles de matériau de base (3), les feuilles de matériau de base (3) comprenant au moins une première feuille de matériau de base (31) et une deuxième feuille de matériau de base (32) et la feuille de matériau de peau de laminage (2) étant disposée entre la première feuille de matériau de base (31) et la deuxième feuille de matériau de base (32). L'utilisation dudit matériau insonorisant (1) permet d'obtenir un faisceau de câbles équipé de matériau insonorisant (6) en intégrant ledit matériau insonorisant (1) avec un faisceau de câbles (7).
