1. An aerodynamic noise measurement system for a vehicle comprising:

  • a wind tunnel that generates a flow of air;

    a test area within the flow of air;

    a plurality of sound reflectors arranged outside of the flow of air, wherein each of the sound reflectors includes a microphone array that measures aerodynamic noise that is generated by a vehicle in the test area and wherein the microphone array generates data signals indicative of the aerodynamic noise; and

    an analyzer system that receives the data signals and generates one of a noise map and an image of the vehicle based on the data signals.
