Reducing noise

In addition to the discharge of climate-affecting substances and health-affecting substances, transportation also causes other environmental effects, of which noise is one of the more noticeable.  Especially in urban areas. Some noise pollution can be eliminated through traffic and urban planning. But since commercial transport in many respects is the life blood of the economy, less noisy vehicles are called for.
How quiet can a truck get?
A hybrid truck is also very quiet.

It is however worth noting that at speeds from 50 km/h, it is the vehicle's tyres that make the noise rather than the driveline. This means that the entire vehicle, including tractor, superstructure, trailer and tyres, must be considered in order to efficiently eliminate noise.
