Population exposure to environmental noise
Rationale
Justification for indicator selection
Exposure to environmental noise can lead to annoyance, stress reactions, sleep disturbance, poor mental health and well-being, and cognitive impairment in children, as well as negative effects on the cardiovascular and metabolic system. Environmental noise causes approximately 16 600 premature deaths in Europe each year, with almost 32 million adults suffering from annoyance and over 13 million suffering sleep disturbance. The WHO has identified noise as the second most significant environmental cause of ill health in western Europe, the first being air pollution. The EU 7th EAP includes the objective of significantly decreasing noise pollution by 2020, moving closer to WHO recommended levels.

Indicator definition
This indicator presents the estimated number of people exposed to harmful levels of environmental noise from industry, roads with more than 3 million vehicles per year, railways with more than 30 000 railway movements per year, airports with more than 50 000 air traffic movements per year and in urban areas with more than 100 000 inhabitants.
Units
Lden: Long-term average indicator designed to assess annoyance and defined by the Environmental Noise Directive (END). It refers to an annual average day, evening and night period of exposure with an evening weighting of 5 dB(A) and a night weighting of 10 dB(A).
Lnight: Long-term average indicator defined by the END and designed to assess sleep disturbance. It refers to an annual average night period of exposure.
dB: Shortened reference to the decibel, a unit of measurement for sound.
Policy context and targets
Context description
The END is the main EU instrument through which noise emissions are monitored and actions developed. It defines environmental noise as 'unwanted or harmful outdoor sound created by human activities, including noise emitted by means of transport, road traffic, rail traffic, air traffic and from sites of industrial activity'. It places an obligation on EU Member States to assess noise levels by producing strategic noise maps for all major roads, railways, airports and urban areas. Based on these noise-mapping results, Member States must prepare action plans containing measures that address noise issues and their effects for those areas where the specific END indicators (i.e. 55 dB averaged across the day, evening and night periods (Lden) and 50 dB averaged across the night period (Lnight)) have been exceeded. The END neither sets limit values for noise exposure, nor prescribes measures for inclusion in the action plans. Finally, Member States are required to select and preserve areas of good acoustic environmental quality, referred to as quiet areas, in order to protect the European soundscape.
High noise levels are defined in the 7th EAP as noise levels for Lden above 55 dB and for Lnight above 50 dB. During the night, environmental noise starting at Lnight levels below 40 dB can cause negative effects on sleep to occur such as body movements, awakenings, self-reported sleep disturbance and, in addition, effects on the cardiovascular system that become apparent above 55 dB. All these impacts can contribute to a range of health outcomes, including premature mortality. The WHO has set a Night Noise Guideline level for Europe at 40 dB Lnight.
Targets
The EU's current 7th EAP contains the objective that by 2020 noise pollution in the EU will have significantly decreased, moving closer to WHO recommended levels. In order to achieve this objective, an updated EU noise policy aligned with the latest scientific knowledge must be implemented along with measures to reduce noise at source, including improvements in city design.

Key policy question
What is the extent of noise pollution in Europe?
Methodology
Methodology for indicator calculation
This indicator is based on data reported by EEA member countries in accordance with Directive 2002/49/EC.
Methodology for gap filling
The indicator is based on data officially reported by countries under the EU Environmental Noise Directive (2002/49/EC). Because of gaps in the reported data, a gap-filling routine is used to estimate the total population exposure to high noise levels.
