Abstract
An aerodynamic noise measurement system for a vehicle uses sound reflectors to determine the sound wave propagation of aerodynamic noise of the vehicle. The vehicle is placed within a test section of a wind tunnel. The air flow of the wind tunnel generates the aerodynamic noise as it passes over the vehicle. An array of sound reflectors is placed outside of the air flow of the wind tunnel. Microphone arrays receive the aerodynamic noise directly from the source and from the sound reflectors. An analyzer system forms an acoustic image of the vehicle based on the aerodynamic noise. A viewing device displays an image of the vehicle with an overlay of aerodynamic noise data in real-time.
