Low Road Noise
Minimal traffic noise
Low road noise is the lowest band the report derives from strategic noise maps. The figure captures road traffic only, not railways or aircraft. Lden sums a full year of that traffic noise into one figure, weighted towards evening and night. The four UK nations each publish their own version of these maps.
What This Means
Traffic noise here is modelled as low, so it should rarely dominate how the house feels. On the quieter part of the band, windows can stay open at night without cars intruding. Towards the top of the band, some road noise will still carry indoors and outdoors. This figure is modelled, not measured at the door, so it is a guide rather than a precise reading. This does not normally affect mortgage approval, buildings insurance or resale.
Score Ranges
Low Noise
45 to 65 dB LdenThe lowest of the three bands; traffic noise ranges from barely noticeable up to clearly audible.
Medium Noise
65 to 75 dB LdenTraffic noise is a regular presence indoors and outside, and intrudes at busier times.
High Noise
Over 75 dB LdenTraffic noise is significant and can affect sleep and outdoor use.
Practical Advice
- Visit at different times of day to confirm how the location feels.
- Ask the seller whether a school run, a delivery route or a pub queue reaches the street.
- Ask your conveyancer's local authority search whether any road scheme is proposed near this property.
Additional Information
Strategic mapping covers major roads, meaning those carrying more than three million vehicles a year. A busy local rat run below that threshold adds nothing to the band. So a low figure is not proof of a quiet street. The linked collection covers England only.
