Localiser Green,
The methods used to estimate the noise footprints around airports is flawed and does not represent the actual footprints.
Footprints also only show you where the noise is, not the "depth" of the noise (like filling a glass with a little water each time an aircraft flies over).
Each event might be quieter than the distant past when it was 1-11 and 707s flying over, but when you have 30 to 1 flying now...........
