Transportation Industry Noise Control

Bus DiagramIncreasing demands for low noise levels either enforced by laws and regulations such as the APTA White Book or by customer demands, cause bus 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 also the fan in the air conditioning system has to be considered. The relative contribution from the different sources varies, depending on the type of bus and the driving conditions, as well as on the location inside the bus.
