Cette thèse porte sur le confort acoustique et, en particulier, sur les matériaux absorbants destinés au traitement des nuisances sonores dans le domaine de l’habitat. L’objectif est double : il s’agit de proposer un matériau bio-sourcé et absorbant dans la gamme des basses fréquences.Notre choix s’est porté sur un matériau poreux bio-sourcé basé sur la fabrication de céramiques poreuses. Il est constitué de cellulose homogène et isotrope. Son procédé de fabrication repose sur la construction d’une empreinte en polyméthacrylate de méthyle permettant un contrôle fin de sa structure interne. Ensuite, nous avons procédé à la caractérisation expérimentale de ses propriétés acoustiques et des paramètres intrinsèques du matériau. L’analyse de ces...
