Increasing demands for low noise levels either enforced by laws and regulations or by customer demands, cause truck manufacturers to look deeper into the possibilities of reducing both the external and internal noise of their vehicles.
The main noise sources are the engine and its accessories, the transmission, the exhaust system, the hydraulic system, the cooling fan and the tires. In some cases the fan in the air conditioning system also has to be considered. The relative contribution from the different sources varies, depending on the type of truck and the driving conditions, as well as the load being transported.
