ABSTRACT:
In a device for establishing noise in a motor vehicle, including a housing having an inlet space, which is in communication via an inlet line with a gas-carrying part of an internal combustion engine arranged in the motor vehicle, and an outlet space, which is acoustically coupled by means of an outlet line to an interior space of the vehicle or the space surrounding the vehicle, the inlet space is separated from the outlet space at least by an acoustically substantially inactive wall. Arranged inside the housing is a sound transmission device, which has vibratable elements, one arranged in the inlet space and onother arranged in the outlet space and connected to each other by a curved connecting element, which is mounted on the acoustically inactive wall, for the transmission of sounds introduced through the inlet line into the inlet space to the outlet space.
