Road & rail noise map for Maidenhead
Town in Windsor and Maidenhead, South East
We analysed 2,406 postcodes in and around Maidenhead, Windsor and Maidenhead against DEFRA's Strategic Noise Mapping (Round 4, 2022). 24% of them (581) have mapped road noise of 55 dB or more by day, and 5% have mapped rail noise. 71% 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 SL6 1EQ (road noise 70.0–74.9 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.
