Abstract
La présente invention a pour objet un dispositif d'insonorisation, notamment pour l'atténuation du bruit produit dans les conduites à air d'une installation d'aération ou analogue. Elle est caractérisée en ce que ce dispositif comporte au moins une conduite d'écoulement en forme de solide de révolution, notamment en forme cylindrique ou conique, ainsi qu'une couche de matériau insonorisant entourant ladite conduite et présentant une épaisseur variable dans des plans perpendiculaires à la direction de l'écoulement, c'est-à-dire dans des plans perpendiculaires à l'axe de la conduite précitée. Elle se rapporte à la construction des installations d'aération, climatisation et analogues.
