Road Noise Exposure Areas on Boulevard de Thouars in Bressuire, 24-Hour Lden

2019 data from the Bureau de Recherches Géologiques et Minières maps noise exposure along the departmental road 938 in Bressuire, Deux-Sèvres. The dataset contains isophone curves for the Lden indicator, representing average noise levels over day, evening, and night periods in 5 dB(A) steps from 55 dB(A). It was created to comply with the European Directive on Strategic Noise Maps and related French environmental codes.

Use Cases

• Assess community noise exposure and health risk based on the Lden indicator described.
• Model noise propagation from road traffic based on isophone curve data.
• Support strategic noise mapping for regulatory compliance based on the EU directive mentioned.
• Analyze spatial patterns of noise pollution in a specific urban corridor based on the geographic focus.

Strengths

• Data is explicitly tied to the European Directive on Strategic Noise Maps, providing a regulatory context.
• Noise levels are represented using the standardized Lden indicator calculated from Lday, Levening, and Lnight.
• Isophone curves are drawn in specific 5 dB(A) steps from 55 dB(A), indicating a structured measurement scale.
