Strategic noise map for Gatwick airport (day)
The Environmental Research and Consultancy Department (ERCD) of the Civil Aviation Authority (CAA) was commissioned by the Department for Transport (DfT) to produce strategic noise maps for Gatwick Airport for 2016.
Noise maps are produced for the following noise indicators: Lday, Levening, Lnight, Lden and annual LAeq,16hr.
This map shows the Gatwick 2016 Lday noise contour. The contours are plotted from 54 to 69 dBA at 3 dB intervals.
The Lday is the equivalent sound level of aircraft noise in dBA for the 12-hour annual average day (0700-1900 local time) period.
