The main subject matter of the invention is a ventilation device including at least one duct intended to channel an air flow in an air flow direction inside the duct, the ventilation device including at least one acoustic attenuation member at least partially arranged around the duct and made up of a network of resonators, each resonator having at least one cavity and one neck connecting the cavity to the duct, the resonators that make up the network of resonators being distributed at least parallel to the air flow direction. A distance separating two necks varies along a direction parallel to the air flow direction and in that a volume of the cavities varies along the direction parallel to the air flow direction.
