Method and device for checking the air noise of a motor vehicle |
摘要 |
A method is used for checking the air noise of a motor vehicle, particularly of a passenger car, which air noise is generated by air flowing onto an outer skin of a vehicle body of the passenger car. In order to optimize this method, targeted air currents are applied by means of a blower to a stationary passenger car in areas where sealing devices extend between stationary vehicle body structures and movable vehicle body elements of the vehicle body, and the air noise occurring as a result of the air currents is measured subjectively and/or objectively. For the implementation of the method, a device is used in the case of which the blower comprising the outflow cross-section is a component of a flow device which is equipped with a blast nozzle for acting upon measuring points on the outer skin.
