DETAILED DESCRIPTION OF THE DRAWINGS

(3) In the example embodiments and figures, the same constituent parts or constituent parts with the same effect may be provided with the same reference signs. The presented elements and their size ratios in relation to one another should not, as a matter of principle, be considered to be true to scale.

(4) FIG. 1 shows a schematic illustration of a system 1 for active noise compensation in the case of a motorcycle, said system having an apparatus 2 for capturing a noise, a computer unit 3 for calculating a compensation sound and an apparatus 4 for producing a compensation sound. By way of example, the apparatus 2 for capturing the noise may be a microphone or a noise sensor. By way of example, the apparatus 4 for producing the compensation sound may be embodied as an actuator or a loudspeaker. Furthermore, the system 1 for active noise compensation has a device 5 for capturing and/or entering a driver-specific parameter or a plurality of driver-specific parameters. The driver-specific parameters may be, for example, a current head position of a driver of a motorcycle when driving, the body size of the driver of the motorcycle and/or a helmet type of the driver of the motorcycle.

(5) Improved noise compensation can be obtained by including driver-specific parameters when calculating the compensation sound that interferes with the noise.

(6) FIG. 2 illustrates a further exemplary embodiment of a system 1 for active noise compensation. In contrast to the exemplary embodiment according to FIG. 1, the system 1 furthermore has a device 6 for capturing a vehicle-specific parameter or a plurality of vehicle-specific parameters. By way of example, the vehicle-specific parameters may be the position or spatial orientation of a windshield of a motorcycle, the vehicle type of a motorcycle, the current inclination of the motorcycle, the current speed of the motorcycle and/or the current engine speed of the motorcycle.
