01 — WHERE IS LONDON LOUD?

ROAD NOISE REACHES
EVERY BOROUGH.

SHARE OF RESIDENTS LIVING WITH ROAD NOISE ABOVE 55 dB · ● = 1%
47%HARROW
10%MERTON

Every London borough averages 60–64 dB — a normal conversation or a loud office, held all day and through the night.

02 — GREEN AREAS VS URBAN

GREEN ISN'T
THE SAME AS QUIET.

47%OF GREATER LONDON IS GREEN COVER

From 6% in the City of London to 68% in Bromley. Yet Harrow — over half green — has the largest share of residents exposed to road noise.

Parks don't silence a city. Distance from traffic does. Step inside one and listen to London drop away.

03 — NON-SILENT STRESSORS

THE BODY DIDN'T
EVOLVE FOR THIS.

Noise raises cortisol, activates the amygdala and strains the heart — even while you sleep. The WHO links every +10 dB of road traffic noise to roughly 8% more ischaemic heart disease.
