The Map of Road Noise in Paris is an Esri map of 2015 road noise levels in the French capital. The map includes four different map layers visualizing road noise levels during a 24 hour period, the noise level at night (22h-6h), all roads exceeding 68 dB in 24 hours and all roads exceeding an average noise level of at least 62 dB at night.
Paris has managed to reduce its overall road noise levels by introducing a number of measures. These include reducing the speed on the Boulevard Périphérique (the ring road) and by reducing overall road traffic in the capital.
