AB  - We discuss the implementation and the performance of an active road noise control system. We review the design of a system based on the Least Mean Square (LMS) adaptive algorithm, suitable for the wideband road noise reduction inside a car cabin. As the system is based on a feedforward control approach, we discuss the method for the selection of the sensors providing the best noise reference signals. We then give a computational complexity analysis of the overall system and discuss the system implementation into a prototype hardware for a mid-size sedan. Performance are then evaluated on different road noise scenarios in real driving situations.
