The aim of this survey was to provide a scientific basis for deciding future policy on aircraft movements at night at Heathrow and Gatwick. The survey sought: a) to establish the nature and scale of sleep disturbance from all causes around Heathrow and Gatwick airports; b) to assess the significance of aircraft noise in causing sleep disturbance; c) to investigate the relationship between exposure to aircraft noise and the degree of sleep disturbance.

Main Topics:

The interview survey also asked questions specifically about disturbance by aircraft noise and the extent to which children were disturbed. An associated noise measurement programme provided the noise exposure (aircraft and background) at each survey site.

17 areas around Heathrow and 8 around Gatwick were selected, within each of which the external nois
