Quietest cities in Brazil
Chronic noise exposure is increasingly recognised as a public health issue. The World Health Organisation's Environmental Noise Guidelines (2018) link sustained exposure above 53 dB(A) daytime to cardiovascular effects, and above 45 dB(A) at night to sleep disturbance. Road traffic, rail corridors, and airport approach paths are the dominant sources in urban Europe.
ClearSpot noise scores are derived from the European Environment Agency's strategic noise maps (END Directive 2002/49/EC) and from OpenStreetMap infrastructure data. They represent the estimated ambient noise pressure at the centre of each city, aggregated to a 0-100% burden score. A score near 0% does not mean silence - it means no major strategic noise source is documented within the default sensitivity radius.
The 50 cities below score lowest on ClearSpot's noise module in Brazil - meaning quieter environments by the standards of strategic mapping. For precise measurements at a specific address, open the live map and zoom in.
