Abstract

The attenuator for air noise, in particular, in the suction channel of an internal combustion engine comprises a duct (12) combined with a resonator chamber incorporating cutouts (13), partition walls (14) and a closure lid (14) distanced from the duct wall. An Independent claim is also included for a method for producing the proposed noise attenuator.
