How these numbers are made. Urbient models noise from OpenStreetMap geometry: roads, rail and pedestrian streets as line sources with per-street traffic adjustments, venues as point sources, aircraft corridors calibrated against the official 2021 strategic noise map, and shielding from 466,000 building footprints. The figures here average 13 sample points spread over the area; any single address can sit well above or below them. This is a modelled estimate and never a certified measurement under DL 9/2007.
