Abstract

L'invention concerne un assemblage d'absorption de bruit présentant une première couche et une seconde couche collée à la première couche. La première couche est constituée d'un matériau fibreux polymère comprenant un mélange de premières fibres et de secondes fibres pour absorber la transmission du son. La seconde couche est constituée d'un matériau polymère non tissé pour former une barrière permettant d'empêcher la transmission du son.
