Abstract: In a device for noise configuration in a motor vehicle which has an internal combustion engine with at least two gas conduits connected to different cylinders of the engine, the gas conduits are interconnected by means of a cross-flow section formed by a housing which encloses the gas conduits and which has at least two chambers in each of which one of the gas conduits is disposed, each of the gas conduits being in communication with the respective chamber by which it is enclosed by means of a respective cross-flow opening and the two chambers being in communication with one another by means of at least one cross-flow opening which is remote from the cross-flow openings of the gas conduits so as to provide for a phase shift of the sound waves of the gas flowing through the housing.

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.

Abstract: In a device for establishing noise in a motor vehicle with a housing, which is divided by at least one sound transmission device into at least two spaces, of which one space is in connection via an inlet line with a gas-carrying part of an internal combustion engine of the vehicle and the other space is acoustically coupled, by means of an outlet line, to an interior space of the vehicle and/or to the space surrounding the vehicle. The outlet line has at least one branch area, from which at least two branch lines extend to different locations in the interior space of the vehicle and/or the space surrounding the vehicle.

Abstract: In a device for establishing noise in a motor vehicle, comprising a housing which is divided by a sound transmission device into at least two spaces, of which one space is in communication with a gas-carrying part of an internal combustion engine arranged in the motor vehicle and the other space is acoustically coupled to an interior space of the motor vehicle via an outlet line, the outlet line is connected via a hollow rigid deflecting element to an interior space lining element, the rigid deflecting element being capable of transmitting forces applied thereto by the sound radiation to the interior space lining element.

Abstract: In a device for establishing noise in a motor vehicle including a hollow body which is divided by at least one sound transmission device into at least two spaces, of which one space is in connection, via an inlet line, with a gas-carrying line of an internal combustion engine arranged in the motor vehicle and the other space is acoustically coupled by means of an outlet line to at least one of an interior space of the vehicle or to the space surrounding the vehicle, a valve device is arranged in the inlet line and/or in the outlet line, which is capable of reducing the cross-section of the respective line c\depending on a control variable.

Abstract: A device for noise configuration in a motor vehicle has a hollow body which is divided into at least two spaces. One space is connected to a gas-carrying part of an internal combustion engine arranged in the motor vehicle, and the other space is coupled acoustically to an interior and/or to an engine space of the motor vehicle and/or to the space surrounding the motor vehicle. The hollow body is divided into the two spaces by an essentially acoustically inactive wall. A vibrational element, which extends into both spaces, is arranged within the hollow body.
