Abstract

In einem Luftfiltergehäuse (1) für eine Brennkraftmaschine, welche aus einer Rohluftschale (2) und einer Reinluftschale (3) besteht, ist im Gehäuse eine Öffnung (5) mit Perforierungen vorgesehen, die von einem luftdurchlässigen Gewebe (8) oder einem Schallelement abgedeckt werden. Durch diese Öffnungen und durch das Gewebe (8) oder dem Schallelement erfolgt eine Luftschallabstrahlung zur Erzielung eines optimierten Außen- und Innengeräusch des Fahrzeugs.
