Abstract

Dieses Einlaßorgan kann durch ein Luftfilter oder eine Sauganlage einer Brennkraftmaschine dargestellt sein. Beide weisen ein Gehäuse mit Wandungen auf, die einen Innenraum des Gehäuses begrenzen, der beim Betrieb der Brennkraftmaschine mit Ansaugluft durchströmt wird.This inlet member can by an air filter or a suction system Internal combustion engine to be shown. Both have a housing with walls, which limit an interior of the housing, which is in operation of the Internal combustion engine is flowed through with intake air.

Zur Erzielung vorteilhafter psychoakustischer Effekte sind die Wandungen mit relativ dünnwandigen Flächen zur Erzielung definierter Frequenzen versehen.To achieve advantageous psychoacoustic effects, the walls are relative Provide thin-walled surfaces to achieve defined frequencies.
