In general, traffic noise can come from four different sources: engine noise, exhaust noise, aerodynamic noise, and tire/pavement interaction noise. Among them, tire/pavement interaction is the dominant noise source for properly maintained vehicles at speeds above 50 km/h [4–7]. Therefore, knowing how to reduce tire/pavement noise plays an
