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. 1The invention relates to an acoustically insulating panel (10), comprising a layer (10a) comprising a first face (10c) and a second face (10d), said layer (10a) being made of a material having a Young's modulus comprised between 1kPa and 100 MPa, a density of between 5 and 1000 kg/m3 and comprising a plurality of diffusers (10f) inserted between the first face (10c) and the second face (10d), the Young's modulus of the diffusers ( 10f) being greater than the Young's modulus of the material of said layer, the diffusers (10f) being arranged in said layer so as to form a periodic network of cells arranged side by side in a direction parallel to said first (10c) and second ( 10d) faces with each cell (10e) comprising at least one diffuser (10f), the panel further comprising sealing means (16) capable of preventing the passage of air from outside the panel into said layer (10a ). Figure to be published with abstract: Fig. 1
