METHODOLOGICAL INFORMATION
--------------------------
To quantify noise pollution, we used the new Noise mapping Geographic Information Systems (GIS) datasets developed by Defra that calculate noise exposure levels and is openly available:
Department for Environment, Food & Rural Affairs. Strategic noise mapping (2022) [Internet]. 2024. Available from: https://www.gov.uk/government/publications/strategic-noise-mapping-2022

For our analyses we used both the day-evening-night level (Lden) and the night level (Lnight). The Lden level is a noise metric used to assess overall annoyance, calculated as the annual average A-weighted sound level over a 24-hour period. 
This measure includes a 5 decibel (dB(A)) penalty for evening noise (7 pm to 11 pm) and a 10 dB(A) penalty for nighttime noise (11 pm to 7 am). The Lnight is a nighttime noise indicator that reflects the annual average A-weighted sound level during the night period (11 pm to 7 am), representing the total sound energy equivalent to the fluctuating noise levels experienced throughout that period.

All geospatial models in this study used Lower Super Output Areas (LSOAs) as the unit of analysis. 
In all analyses, we used the LSOA boundaries published by the Office for National Statistics as at March 21, 2021:
