Abstract

Die Erfindung betrifft einen Schalldämpfer zur Verringerung von Luftgeräuschen, insbesondere im Ansaugtrakt einer Brennkraftmaschine, mit einem Einlaß (10) und einem Auslaß (11), einer zwischen Einlaß (10) und Auslaß (11) angeordneten Luftleitung (12), wobei die Luftleitung (12) Mittel zur Verringerung von Luftgeräuschen beinhaltet, wobei im Verlauf der Luftleitung (12) wenigstens ein Teilsegment des Umfangs dieser Luftleitung (12) durch einen korrespondierenden Resonatorgehäusedeckel (15) mit einem radialen Abstand zur Wand der Luftleitung (12) zu einer Resonatorkammer verschlossen ist, wobei die Teilsegmente voneinander unabhängig sind und die Resonatorkammer durch Ausnehmungen (13) in der Wand der Luftleitung (12) mit dem Innenraum der Luftleitung (12) verbunden ist.
Außerdem betrifft die Erfindung ein Verfahren zur Herstellung des oben genannten Schalldämpfers.
