Lden noise indicator data for RD 743 between Niort and Parthenay, mandated by the European Directive on Strategic Noise Maps. The Bureau de Recherches Géologiques et Minières collected these isophone curves representing overall noise discomfort in 5 dB(A) steps from 55 dB(A). The dataset was last updated on April 4, 2019.
Use Cases
- Modeling noise exposure zones based on the Lden indicator described in the directive.
- Assessing public health risks from road noise based on the overall discomfort metric.
- Creating noise maps for strategic planning as required by EU regulations.
- Analyzing noise levels across day, evening, and night periods using the Lday, Levening, Lnight components.
Strengths
- Data collection follows specific EU directives and French implementing texts (Decree No 2006-361, Circular of 7 June 2007).
- Indicator values are expressed in standardized dB(A) units.
- The dataset is provided by a recognized geological and mining research bureau.
