Highway Traffic Noise Information
Noise is considered unwanted sound. One of the most significant sources is from transportation, particularly traffic noise.
Highway noise comes from three sources: the engine, the exhaust system and the interaction of the tires and pavement. Once typical highway speeds are reached, the predominate noise from light trucks and cars is from the tire/pavement interaction. Heavy trucks produce a high volume of noise from all these sources. Helping to alleviate these negative impacts is the objective of noise abatement.
