Depending on the speed the wind noise can become the most prominent noise source inside the car. To optimize the aerodynamic outline of each vehicle wind tunnels offer the perfect test conditions. gfai tech provides customized solutions for highest precision in sound source localization in wind tunnels, including shear layer correction, 3D model generation and fitting, correlation analysis and many other features to find the best results.
