Abstract (en)
[origin: WO03023217A1] The invention relates to a fluid guideline (1) comprising at least two structural members (2,3,8) consisting of essentially acoustically tight material and at least one opening (11,11') for sound dissipation. The impedance of the flow resistance of the fluid flowing through the fluid guideline varies, especially in the form of a sudden impedance variation, between two adjacent structural members. The at least one opening in the region of the impedance variation is arranged between two adjacent structural members.
