Road & rail noise map for Lostwithiel
Town in Cornwall, South West
We analysed 214 postcodes in and around Lostwithiel, Cornwall against DEFRA's Strategic Noise Mapping (Round 4, 2022). 21% of them (44) have mapped road noise of 55 dB or more by day, and 1% have mapped rail noise. 78% of postcodes have no mapped road or rail noise at all — though that reflects major-source modelling, not guaranteed quiet. The highest modelled level we found is at PL22 0AE (road noise 65.0–69.9 dB by day).

What this data does — and doesn't — cover
- Modelled, not measured.These are DEFRA's computer-modelled estimates (Round 4, 2022), not microphone readings at your door.
- Major sources only. The model covers major roads, major railways and large urban areas. Smaller local roads, neighbours, pubs, building sites and aircraft are not included.
- No mapped noise ≠ quiet. If a location shows no band, it means it falls outside the mapped contours — not that it is silent.
- 2022 snapshot.New roads, developments or traffic changes since 2022 won't show. The next DEFRA round is due around 2027.
