Understanding UK Noise Levels
NoiseCheck's postcode values are illustrative assignments based on source lookup groups and preset ranges. They do not measure environmental noise, represent validated predictions, or support property, legal or health decisions.
The site's model gives an average assigned value of 53 dB across 2,289 postcode districts. Source categories include road, rail, aircraft, industrial and ambient lookup groups.
What Affects Noise Levels?
- Road traffic — the most common noise source, especially near motorways (M25, M1, M6) and A-roads
- Aircraft — airport lookup groups do not establish overhead routes or noise at a home; consult official airport tracking and noise maps
- Railways — mainline routes like the West Coast and East Coast Main Lines generate noise for adjacent communities
- Industrial activity — ports, factories and commercial zones contribute to local noise
