The main source of environmental (ambient) noise is transport. Road traffic is the most widespread source. Percentage of the population exposed to different noise levels is high. People in urban areas are exposed to the highest levels of noise, because of concentration of population and traffic in the cities. Most worrying is a significant increase in noise at night, because people are most sensitive to noise at that time.

Environmental indicators in Slovenia

The web portal Environmental Indicators in Slovenia provides access to over 100 indicators which use graphs, maps and comments to present the environmental trends in Slovenia. The indicators are organized into thematic groups – chapters covering environmental components (e.g. water, air), environmental issues (e.g. climate change, nature protection, loss of biodiversity, waste management) and the incorporation of environmental content in the formulation of sector policies (e.g. transport, agriculture, tourism, energy, instruments of environmental policy). The indicators represent one of the four pillars of our environmental reporting, based on the demands in article 106 of the Environment Protection Act (Official Gazette of the RS, No. 41/2004 with changes). Based on numerical data, they indicate state, characteristics and trends of environmental development in Slovenia. They are produced via interlinkages among the data and observations as shown on Figure 1. More
