Abstract

L’invention concerne un panneau acoustiquement isolant (10), comprenant une couche (10a) comprenant une première face (10c) et une seconde face (10d), ladite couche (10a) étant réalisée dans un matériau ayant un module d'Young compris entre 1kPa et 100 MPa, une masse volumique comprise entre 5 et 1000 kg/m3 et comprenant une pluralité de diffuseurs (10f) intercalés entre la première face (10c) et la seconde face (10d), le module d'Young des diffuseurs (10f) étant supérieur au module d'Young du matériau de ladite couche, les diffuseurs (10f) étant agencés dans ladite couche de manière à former un réseau périodique de cellules agencées côte à côte selon une direction parallèle auxdites première (10c) et seconde (10d) faces avec chaque cellule (10e) comprenant au moins un diffuseur (10f), le panneau comportant en outre des moyens d'étanchéité (16) aptes à interdire le passage d'air depuis l'extérieur du panneau dans ladite couche (10a). Figure à publier avec l’abrégé : Fig. 1
