  • the invention relates to a computer program product.
  • Motor vehicles such as passenger cars (cars) are used at least in part to transport people. These are usually located in an interior of the motor vehicle in which one or more seats are arranged for the people.
  • noises are generated that enter the interior of the motor vehicle and are found there to be annoying. It is also possible that such noises, especially if they are comparatively monotonous, lead to premature fatigue of the people in the interior.
  • Corresponding noises are, for example, operating noises from a main drive of the motor vehicle, which has an internal combustion engine, for example. Furthermore, such noises are due to turbulence caused by wind noise, which arise due to the shape of the motor vehicle when moving. Rolling noises of any tires on a surface also count among these noises.
  • Insulation is usually provided to reduce the noise that can be heard in the interior. This is arranged, for example, in the area of an engine compartment, and/or the interior is partially surrounded by appropriate insulation, which is also partially arranged inside a door of the motor vehicle.

  • efficiency is reduced.
  • due to an increase in the weight of the door its operation is made more difficult, so that comfort is reduced.
  • An alternative approach provides for the noise occurring in the interior to be detected by means of a plurality of microphones, which are arranged, for example, in a roof liner or at other positions in the interior.
  • the sound signals captured by the microphones are transmitted to a central control unit, where an opposing sound signal is calculated.
  • This is sent to a multi media system, by means of which the anti-noise signal is transmitted to several loudspeakers, which serve to output audio signals into the interior of the motor vehicle. Due to the counter-noise signal emitted by the loudspeakers, there is counter-noise which at least partially compensates for the noise in the interior.
