Method and assistance system for automatic noise optimization, and motor vehicle

A method for optimizing noise in a motor vehicle, comprising:

• automatically, during operation of the motor vehicle, capturing and analyzing acoustic signals for acoustic excess;
• in response to detecting an acoustic excess via the analysis, capturing a current load requirement and at least one current operating parameter value for at least one motor vehicle system that complies with the load requirement;
• varying at least one operating parameter, with continued compliance with the load requirement, by a self-learning adaptation device so as to reduce the acoustic excess;
• in response to the reduction of the acoustic excess, setting a corresponding new operating parameter as a new operating strategy for the motor vehicle system for complying with the respective load requirement, wherein the new strategy is set to be used in response to the occurrence of the respective load requirement;
• performing noise optimization in a predefined optimization operating mode of the motor vehicle in which different predefined load requirements are run through in a predefined program,
• wherein during operation of the motor vehicle, a user setting of:
• a degree of opening of a side window, an air flow intensity of a ventilation device and/or a volume of a media playback device, is captured, and
• wherein the at least one operating parameter value is varied only when the noise level generated by the user setting is less than a predefined threshold value and/or noise corresponding to the acoustic excess is not drowned out by the noise level generated by the user setting.
