Beschreibung
Zusammenfassung:	A device for the targeted transmission of sound from an induction tract of an internal combustion engine in a motor vehicle into the interior of the motor vehicle, comprising a hollow transmission body which communicates with the induction tract on the intake side and which emits sound on the output side into the vehicle interior. In order to improve the sound emission of a device of this type, the invention proposes that the transmission body had a conduit section with a conduit cross-section and a chamber section with a chamber cross-section, whereby the chamber cross-section is larger than the conduit cross-section. The conduit section communicates with the induction tract on the intake side and opens into the intake side of the chamber section. The output side of the chamber section emits the sound into the vehicle interior.
