Abstract

The invention relates to a ventilation duct (10) for the air conditioning system of the passenger compartment of a vehicle, that comprises noise reduction means, characterised in that the duct includes an upstream section (12) with an inlet mouth (14) and a turning section (20), and in that the noise reduction means include a reflection area (30) provided in the turning section (20) opposite the upstream section (12) and capable of reflecting at least a portion of the incident waves (11) towards the inlet mouth (14).
