Abstract:
A device for noise transmission of an intake system of an internal combustion engine to the interior of a motor vehicle has a transmission line having an inlet at a first end and an exit provided with a mouth at a second end. A diaphragm is arranged at the second end to close off the mouth and to enable noise transmission. The inlet of the transmission line communicates with the intake system of the internal combustion engine. A protective device is arranged at the second end to protect the diaphragm.
