These statistics are from Leeds Bradford Airport's application to expand which it withdrew in 2021. This is the latest in-depth study of the impact of increasing passenger numbers to seven million. The statistics will be the same if the airport continues its plan to expand, which is its current declared strategy.
- At night, the area surrounding the airport where people will experience LOAEL (the lowest noise dose at which there is an observed adverse effect) will increase after development by 8.6km2, to 56.2km2. This means that 123,000 people will fall into this category, and due to the increased incidence of noise the number of people being Highly Sleep Disturbed will be 42,000 and the number of people being Highly Annoyed will be 93,500 [1].
- 11897 households will experience increased day time noise in 2030 (Figure 10.4-52 WebTAG workbook for the Development).
- An extra 2,600 people will be subject to at least 51dB (LAeq16hr), an extra 1900 to at least 54dB, an extra 700 to at least 57dB and an extra 200 to at least 60dB (see Low birth weight for babies of mothers in proximity to the airport) (Table 10.21 in the noise and vibration chapter).
- 26,100 more people will hear between 1 and 50 more planes which are loud enough to disturb them (above 65dB LAmax) on an average summer day (Table 10.23 in the noise and vibration chapter).
- 7,200 more people will hear between 50 and 100 planes loud enough to disturb them (above 65dB LAmax) on an average summer day (Table 10.23 in the noise and vibration chapter).
- 34,000 more people to be subjected to an increase in the amount of day time plane noise loud enough to have an adverse effect on them (Table 10.22 in the noise and vibration chapter).
- 36,700 more people will experience night time plane noise loud enough to have an observable adverse effect on them, and 700 more people will experience significant adverse effects (Table 10.24 in the noise and vibration chapter).
- 123,000 more people will be exposed to an increase in night time plane noise at levels which have observable adverse impacts (Table 10.25 in the noise and vibration chapter).
