ABSTRACT:
The invention is an apparatus and a method for carrying out a vibroacoustic inspection of a motor vehicle that features at least a front and a rear axle, with a test stand that is directly or indirectly connected to at least one of the two axles by means of a force flow and relative to which the motor vehicle is tied, wherein at least one vibration generator of a first type is provided along the force flow in order to generate vibrations below 50 Hz. The invention includes at least one second vibration generator of a second type, which is provided along the at least one force flow or parallel to the force flow, for generating vibrations above 30 Hz, preferably above 100 Hz, and the at least one second vibration generator is operatively connected to the motor vehicle.
