Deux-Sèvres, France, contains geospatial data representing areas exposed to road noise from departmental road 759 in Thouars. The dataset provides isophone curves for the Lden noise indicator, calculated in 5 dB(A) steps from 55 dB(A) over a 24-hour period. It was produced by the Bureau de Recherches Géologiques et Minières and last updated in April 2019.
Use Cases
- Create strategic noise maps based on the Lden indicator as required by the European Directive.
- Assess population discomfort from road noise exposure based on the 24-hour Lden calculation.
- Model noise propagation from specific roads like Rue Camille Pelletan and Boulevard Pierre Curie.
- Evaluate compliance with French environmental codes and decrees related to noise prevention.
Strengths
- Data is collected in accordance with specific French legal texts (Decree No 2006-361, Circular of 7 June 2007).
- The Lden indicator is calculated from defined day, evening, and night periods (6h-18h, 18h-22h, 22h-6h).
- Isophone curves are drawn in specific 5 dB(A) steps from 55 dB(A).
