Why are busses so loud?

Cars measure around 70-80 dB, while busses can reach as high as 80-95 dB. The source of this noise pollution comes from three sources, including the tires, how air comes into contact with the vehicle and the power transfer system, which includes the engine, exhaust system and air blower.
