ABSTRACT:
A device for the targeted sound transmission from an intake tract of an internal combustion engine to the interior of a motor vehicle. The device comprises at least one hollow transmission conduit, which communicates on the input side with the intake tract and to which at least one resonator chamber, which emits the sound to the motor vehicle interior, is connected. In order to achieve improved modulation of the sound that is emmitted to the motor vehicle interior, the inventive device has several resonator chambers operating in parallel, at least two of which differ from one another with respect to the tuning of their frequencies.
