2. Using commercially available sound meters, we have devised a method for noise data collection.

3. Royal Docks area in London Noise Map
The London Noise Map depicts areas around LCA as quiet! It only takes into consideration noise generated by traffic and does not reflect the ambient noise levels that communities are exposed to.

This data collection sheet (with the final design by Christian Nold) includes perceptions and feelings about the noise.

9. Other sources of noise were recorded but aircraft related noise was the predominant source

10. A different visualisation that depicts clusters where noise levels are deemed acceptable <60dbA and cluster where there is a general consensus that levels exceeding 60dbA are perceived as annoying.

11. Comparable sound perceptions from Royal Docks and Pepys Estate in Deptford, Lewisham.

12. Graph shows data collected from March through to April this year (2010); the difference in terms of noise levels during normal flight operations at both Heathrow and LCA, and during a period of no flights. Levels rarely exceed 55dBA

The Royal Docks Community map has recently been used by community members to record the levels of noise they are being exposed to
