Abstract

Dispositif réducteur de bruit (100) pour équiper l'extrémité d'une conduite (5) traversée par un flux gazeux comprenant un déflecteur (2, 3, 4) coupant l'axe (xx) du flux à l'extrémité de la conduite (5). Le déflecteur est formé de cavités de résonateur (31). Ces cavités sont couvertes par une couche de mousse absorbante (4) et les cols (34) des cavités (31) traversent la couche de mousse absorbante (4).
