The noise maps were calculated with two indices according to the calculation methods of the regulation (the Grand-Ducal Regulation of 2 August 2006 implementing Directive 2002/49 / EC of the European Parliament and of the Council of 25 June 2002 on the management of environmental noise and the law of 2 August 2006 modifying the modified law of June 21, 1976 relating to the fight against noise).
Lden: average noise index for an average day of 24 hours evaluated over a year (night penalized by 5 dB [A] in the evening and 10 dB [A] at night) Lnight: average noise index for an average night of 8 hours evaluated over a year

Preventive measures include, first and foremost, action at the spatial planning level (e.g. general development plan, special development plan, land use plan, model building regulations), and municipal planning (sectoral plans). These measures are part of an approach to preserve quiet areas on the urban plan.
Measures for remediation of existing noise problems include focusing on priority areas of noise management, i.e. areas with high noise levels and a large number of people affected. Action plans focus on noise reduction measures at the source, i.e. where the noise is created, which has the advantage of having an immediate impact on the external sound environment and are generally more favorable in terms of cost-effectiveness.
Where noise reduction at source is insufficient, protective infrastructures (e.g. screens and noise barriers) may be considered, provided that their integration into the environment or urban landscape is respected.
Compared to 2011, 2016 noise mapping results showed a reduction of isocontours, and therefore impacted surfaces in km2, by 6 to 9 percent.
We have achieved a reduction in the number of people impacted by the highest level of noise at night from 8,900 to 5,700 and a reduction in the number of people impacted by medium levels from 3,100 to 2,400. It was also taken into account that the total number of people exposed increases as a result of population growth around the airport.
