Authors Abstract
Content
A method of breaking down car interior noise measurements into aerodynamic noise, residual noise and aspiration noise is presented. Correlation between car interior aerodynamic noise extracted from “on the road” measurements and car interior aerodynamic noise measured in a wind tunnel indicate the validity of the method. Limitations of the method in both frequency and car airspeed are identified.
