1. A device for controlling a volume of a car radio of a motor vehicle as a function of a driving noise, comprising:
- an acceleration sensor detecting the driving noise which is provided into an interior of the motor vehicle as a structure-borne noise and generating a sensor signal which relates to the structure-borne noise, the acceleration sensor being mechanically connected to a body of the motor vehicle; and
a signal processing circuit receiving the sensor signal and controlling the volume of the car radio disposed in the motor vehicle as a function of the sensor signal.
