- dose-effect relation
shall mean the relationship between the value of a noise indicator and a harmful effect;
- environmental noise
shall mean 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 such as those defined in Annex I to Council Directive 96/61/EC of 24 September 1996 concerning integrated pollution prevention and control;
- harmful effects
shall mean negative effects on human health;

- Levening
(evening-noise indicator) shall mean the noise indicator for annoyance during the evening period, as further defined in Annex I;
- limit value
shall mean a value of Lden or Lnight, and where appropriate Lday and Levening, as determined by the Member State, the exceeding of which causes competent authorities to consider or enforce mitigation measures;

- noise indicator
shall mean a physical scale for the description of environmental noise, which has a relationship with a harmful effect;
- noise mapping
shall mean the presentation of data on an existing or predicted noise situation in terms of a noise indicator, indicating breaches of any relevant limit value in force, the number of people affected in a certain area, or the number of dwellings exposed to certain values of a noise indicator in a certain area;
- quiet area in an agglomeration
shall mean an area, delimited by the competent authority, for instance which is not exposed to a value of Lden or of another appropriate noise indicator greater than a certain value set by the Member State, from any noise source;
- quiet area in open country
