The term "road noise" refers to the unwanted sound generated by vehicles traveling on roads or highways. This type of noise is caused by a variety of factors, including the movement of tires over pavement, engine and transmission sounds, aerodynamic drag, and wind noise. Road noise can be particularly bothersome for those living near busy roadways, as it can disrupt daily activities such as conversation or relaxation. To minimize road noise, measures such as sound barriers, proper road design, and vehicle insulation can be implemented.
