Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate her Department has made of the number of people in Harrow constituency who will be exposed to aircraft noise above 43dB LAeq in the next five years.

The government does not routinely produce noise forecasts for airports. However, the draft Heathrow Expansion National Policy Statement Appraisal of Sustainability Noise Annex shows a comparison of 43dB LAeq noise contours for 2024 and 2055 and estimates the number of people exposed to this level of noise.
