Abstract
An apparatus and method for testing flow noise of a motor vehicle are provided. The apparatus includes a blast nozzle device having at least one blast nozzle, and a transport device. The blast nozzle device is designed for the targeted impingement of the outer skin of the motor vehicle by air flow, and the transport device is designed such that the blast nozzle device and the motor vehicle may be moved relative to one another. A microphone array is positioned in the interior of the motor vehicle and measures the flow noise in the interior of the motor vehicle. The microphone array is preferably a spherical array. The flow noise in the interior of the motor vehicle generated by the air flow is measured by use of the microphone array.
