In accordance with European legislation, the Environment Agency has updated the strategic noise maps for the fourth cycle of Directive 2002/49/EC of the European Parliament and of the Council of 25 June 2002 relating to the assessment and management of environmental noise. These maps refer to the year 2021 and indicate, with the help of a standardised colour scale using the Lden indicator, the exposure to ambient noise in decibels of railways located within agglomerations. The indicators used to describe the annoyance caused by exposure to noise are : Lden in decibels (dB), a representative average noise indicator for a 24-hour day, evaluated over a full year and for which the evening period is penalised by 5 dB(A) and the night period is penalised by 10 dB(A); and the Lnight in decibels (dB), a representative average noise indicator for an 8-hour night, assessed over a full year and associated with sleep disturbance. The indicators are based on three periods of the day: a day" period of 12 hours (7am to 7pm), an "evening" period of 4 hours (7pm to 11pm) and a "night" period of 8 hours (11pm to 7am)." https://environnement.public.lu/fr/loft/bruit/valeurs-limites-bruit.html

These maps refer to the year 2021 and indicate, using a standardised colour scale based on the Lden indicator, the exposure to ambient noise in decibels of major roads with more than 3 million vehicles per year located within agglomerations. The indicators used to describe the annoyance caused by exposure to noise are : Lden in decibels (dB), a representative average noise indicator for a 24-hour day, evaluated over a full year and for which the evening period is penalised by 5 dB(A) and the night period is penalised by 10 dB(A); and the Lnight in decibels (dB), a representative average noise indicator for an 8-hour night, assessed over a full year and associated with sleep disturbance.
