How to read this index
The Sossego Index runs from 0 to 100 and is an estimate built from open data, not an on-site measurement. 100 means 48 dB(A) or less, the level of a calm residential area. 0 means 86 dB(A) or more, the level of a heavy traffic avenue. Each neighbourhood's value is the median of nine points around its centre.
