Truck noise pollution · consultants
Canarina Environmental Software provides environmental consultancy services for projects involving the assessment of truck noise. Trucks contribute to air, noise, and water pollution similarly to automobiles. Trucks may emit lower air pollution emissions than cars per equivalent vehicle mass, although the absolute level per vehicle distance traveled is higher, and diesel particulate matter is especially problematic for health. Continuous sounds are those from tires rolling on the roadway, and the constant hum of their diesel engines at highway speeds. Less frequent noises, but perhaps more noticeable, are things like the repeated sharp-pitched whistle of a turbocharger on acceleration, or the abrupt blare of an exhaust brake retarder when traversing a downgrade. With respect to noise pollution, trucks emit considerably higher sound levels at all speeds compared to typical car; this contrast is particularly strong with heavy-duty trucks.
