摘要： The invention relates to an acoustic attenuation device (1) for a turbocharger, or for a supercharger, arranged along an air intake line of a vehicle. The attenuation device (1) comprises a gas supply pipe (2) having a peripheral wall (21) and a diameter (d2), the pipe (2) comprising at least one annular chamber (3) defined by a diameter (d3) greater than the diameter (d2) of the pipe (2), the or each annular chamber (3) being sealed by a wall (5) comprising porous material that is positioned in the extension of the peripheral wall (21) of the pipe (2), according to a diameter (d5) substantially equal to the diameter of the pipe (2), in order to allow air to flow between the pipe (2) and the or each peripheral chamber (3).
