The data set includes the noise contours which have been reported by countries under the terms of the Environmental Noise Directive (END) by the 33 EEA member countries (EEA-33) excluding Turkey for the third round of noise mapping in 2017. The data set includes submissions from the countries until 01/01/2019. According to the END, for major sources of noise (i.e. major roads with more than 3 000 000 vehicle passages a year, major railways with more than 30 000 train passages per year and airports with more than 50 000 movements per year), countries have to submit noise contour maps for at least the >55 dB, >65 dB bands. Noise contour maps for roads, railways, airports and industries in urban agglomerations of more than 100 000 inhabitants need to be represented for at least 60, 65, 70 and 75 dB bands for the day-evening-night period. The data set is provided in GDB and GPKG files, with all the reported noise contours in vector format by country or region/state (in the case of BE and DE), for major sources at agglomeration level and national level and for both indicators Lden (day-evening-night noise level: the long-term average indicator designed to assess annoyance defined by the END; it refers to an A-weighted average sound pressure level over all days, evenings and nights in a year, with an evening weighting of 5 dB and a night weighting of 10 dB) and Lnight (night noise level: the long-term average indicator defined by the END and designed to assess sleep disturbance; it refers to an A-weighted annual average night period of exposure).

The data set includes the rasterized noise contours which have been reported by countries under the terms of the Environmental Noise Directive (END) by the 33 EEA member countries (EEA-33) excluding Turkey for the third round of noise mapping in 2017. The data set includes submissions from the countries until 01/01/2019. According to the END, for major sources of noise (i.e. major roads with more than 3 000 000 vehicle passages a year, major railways with more than 30 000 train passages per year and airports with more than 50 000 movements per year), countries have to submit noise contour maps for at least the >55 dB, >65 dB bands. Noise contour maps for roads, railways, airports and industries in urban agglomerations of more than 100 000 inhabitants need to be represented for at least 60, 65, 70 and 75 dB bands for the day-evening-night period. Due to its size, the data set is provided in TIFF format (10 m cell size) files by country or region/state (in the case of BE and DE), with the noise contours for major sources at agglomeration level and national level, for both indicators Lden (day-evening-night noise level: the long-term average indicator designed to assess annoyance defined by the END; it refers to an A-weighted average sound pressure level over all days, evenings and nights in a year, with an evening weighting of 5 dB and a night weighting of 10 dB) and Lnight (night noise level: the long-term average indicator defined by the END and designed to assess sleep disturbance; it refers to an A-weighted annual average night period of exposure).
