The types of noise that are experienced can be classified into some fairly broad categories. For example, environmental noise which is generated by transport and industry.

Noise can cause annoyance, interrupt conversation, disturb sleep and, in extreme conditions, cause physical damage to those affected. The types of noise that are experienced can be classified into some fairly broad categories – for example, occupational noise which is experienced at work, neighbour or neighbourhood noise caused by people in or around their homes, environmental noise (often called ambient noise) which is generated by transport and industry.

Environmental noise has been addressed by a combination of:

  • reducing the level of noise generated by individual vehicles, aircraft etc;
  • traffic management schemes; and 
  • addressing noise at the planning stage of new noise generating or noise sensitive developments.

Such action has considerably reduced the output of noise from individual sources but often failed to reduce the overall environmental noise because of other factors such as the growth in the number of vehicles on our roads.
