To ask the Secretary of State for Health and Social Care, whether his Department has made an assessment of any change in the proportion of the population exposed to road, rail and air transport noise of (a) 65dB(A) or more during the daytime and (b) 55dB(A) during the night-time, as set out in the Public Health Outcomes Framework.

The Public Health Outcomes Framework (PHOF) includes two indicators which show the percentage of the population exposed to road, rail and air transport noise above a certain level. Indicator B14b shows the percentage of the population exposed to noise levels of 65 dB(A) or more during the daytime. Indicator B14b shows the percentage of the population exposed to noise levels of 55 dB(A) or more during the night-time. The PHOF online tool includes data for three assessment years: 2016, 2011 and 2006/7. This data shows that the percentage of the population exposed to 65 dB(A) or more during the daytime, changed from 5.2% in 2011 to 5.5% in 2016. The percentage of the population exposed to 55 dB(A) or more during the night-time changed from 8% in 2011 to 8.5% in 2016.

Due to differences in the definitions of major roads, railways and airports and in modelling methodologies between the assessment years, comparisons should be interpreted with caution.
