Abstract
This method includes the placing of the first porous layer () onto one part of a wall of a mold cavity having the shape desired by the soundproofing component, the first layer () not occupying the entire cavity, and the injection of a foaming polymer composition into the cavity of the mold to form the second open-cell porous layer (). The two steps of placing the practically airtight intermediate layer () onto the first porous layer () and of injecting a polymer composition in order to form the second porous layer () are carried out simultaneously in a single step of injecting the foaming polymer composition.
