Abstract (en)
[origin: FR2876748A1] The conduit (5) has additional air inlets (6) along its length such that the radiated noise through and in the vicinity of each inlet is lower than the noise at a mouth (7). The level of radiated noise through one additional air inlet is identical to the other air inlets. The inlets are disposed at intervals along the conduit and are distributed radially in the form rows defining the intervals. An independent claim is also included for an air inlet device for internal combustion engine or air conditioner of a motor vehicle comprising an anechoic gaseous fluid conveying conduit.
