Depending on the driving speed, the wind noise can become the most prominent noise source inside the car. Wind tunnels offer the perfect test conditions to examine the aerodynamic outline of each vehicle type. gfai tech provides customized solutions for highest precise 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.
