Abstract

L'invention concerne un dispositif (1) comprenant un format (3) souple d'un complexe comprenant, associés successivement l'une sur l'autre : une couche d'isolation (4) acoustique souple et étanche ; une couche d'absorption acoustique interne (5) souple et poreuse ; une couche de protection interne (6), destinée à être tournée vers ledit composant, souple et perméable à l'air de manière à permettre un passage des ondes acoustiques au sein de ladite couche d'absorption, ledit format étant pourvu de moyens de maintien (7) permettant de lui conférer par déformation desdites couches une géométrie tridimensionnelle définissant au moins en partie un logement (8) de réception dudit composant, ledit logement étant pourvu d'au moins une ouverture (9), ladite couche d'isolation étant revêtue d'une couche d'absorption acoustique externe (10) souple et poreuse.
