A device for controlled transmission of sound from an intake tract (1) of an internal combustion engine (9) of a motor vehicle to an interior (15) of the vehicle, with a hollow sound transmitting body (12) which communicates at the input end (13) with the intake tract (1) and at the output end (17) it radiates sound to the vehicle interior (15);

• characterized in that
• the sound transmitting body is designed airtight with respect to the outside;
• the sound transmitting body has a line section (18) with a line cross section (21) and a chamber section (19) with a chamber cross section (22);
• the chamber cross section (21) is larger than the line cross section (22);
• the line section (18) communicates at the input end with the intake tract (1) and at the output end it opens into the input end of the chamber section (19) and
• the output end of the chamber section (19) radiates sound toward the vehicle interior (15).
