Abstract (en)
[origin: WO2019155135A1] The invention relates to an aeraulic and acoustic treatment system for an air management system of a vehicle, comprising a duct (2) guiding an outside air flow or a recycling air flow (11) from the interior of the vehicle via an opening (10) made in said duct (2) and opening into the interior, a pivoting recycling flap (3) moving between an opening position and a closing position, said air management system also comprising a source of noise (6) emitting a sound signal in the duct (2), and a conduit (7), said conduit (7) having a first end attached to the duct (2) on one side of the opening (10) and a second free end, leaving a passage between said conduit (7) and said opening (10), said passage opening into the interior, said conduit (7) being long enough to extend over the opening (10), and beyond, over a portion of the duct (2), in such a way as to create a recycling air intake off-centre beyond the opening (10) when said pivoting recycling flap (3) is in the opening position.
