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 are 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. ________________________________________ Geospatial Analysis Information: All geospatial models in this study used Lower Super Output Areas (LSOAs) as the unit of analysis.
