This layer contains the existing noise barriers in the rail network, which have been summarized by the authorities and used for the 2021 noise mapping under the Environmental Noise Directive 2002/49/EC.

When drawing up the strategic noise maps for the fourth round 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, the Environmental Administration also took a closer look at the impact of Touch & Go flights. These maps refer to the year 2021 and show the exposure to aircraft noise during the daytime period in decibels per year using the Lden indicator.

These maps refer to the year 2021 and show the exposure to aircraft noise during the night period in decibels per year using the Lngt indicator.

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 aid of a standardised colour scale using the Lngt 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 Lngt indicator, the ambient noise exposure 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.

The Environment Agency has commissioned a specialized and approved external expert to carry out noise level measurements at 5 selected immission points. The purpose of the mission was to measure the sound pressure at a representative measurement point, in order to control the rail noise levels of the main traffic axes. For the measurement and calculation methods, the external expert used the standards ISO 1996-1: 2016 and ISO 1996-2: 2017.

The Environment Agency has commissioned a specialized and approved external expert to carry out noise level measurements at 10 selected immission points. The purpose of the mission was to measure the sound pressure at a representative measurement point, in order to control the aircraft noise levels around the Findel. For the measurement and calculation methods, the external expert used the standards ISO 1996-1: 2016 and ISO 1996-2: 2017.
