How noisy is RH10 7AA?

DEFRA's 2022 noise model puts the loudest mapped source at RH10 7AA in the 65.0–69.9 dB band. Mapped noise here: moderate road noise by day, moderate at night; high rail noise by day, high at night.

Is this a measurement of actual noise?

No. These figures come from DEFRA's Strategic Noise Mapping Round 4 (2022), a computer model of noise from major roads and railways. It estimates average levels over a year, not what you'd hear on any given day.

What noise sources are missing from this data?

The model only covers major roads, major railways and large urban areas. Neighbour noise, pubs and venues, building sites, aircraft and smaller local roads are not included.

Noise levels in RH10 7AA

Mapped noise here: moderate road noise by day, moderate at night; high rail noise by day, high at night.

According to DEFRA's Strategic Noise Mapping (Round 4, 2022), the postcode RH10 7AA has modelled road noise of 60.0–64.9 dB by day and 55.0–59.9 dB at night, and rail noise of 65.0–69.9 dB by day and 60.0–64.9 dB at night. These are modelled estimates of noise from major roads and railways, not measurements.

Mapped noise bands at RH10 7AA

Source	Modelled level	What that means
Road (day, 07:00–23:00)	60.0–64.9 dB	Roughly constant busy-road hum — about the level of normal conversation. Clearly noticeable with windows open and audible through single glazing.
Road (night, 23:00–07:00)	55.0–59.9 dB	A steady background hum, like a busy office. Audible outdoors and with windows open; most people acclimatise but it is rarely truly quiet.
Rail (day, 07:00–23:00)	65.0–69.9 dB	Loud enough to intrude — think standing 10–20 metres from a busy main road. Conversation outdoors takes more effort; good glazing makes a real difference indoors.
Rail (night, 23:00–07:00)	60.0–64.9 dB	Roughly constant busy-road hum — about the level of normal conversation. Clearly noticeable with windows open and audible through single glazing.

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.
