Aircraft noise is measured for many reasons - it is important to know whether the noise levels are increasing or decreasing over time, and if so, by how much. We have three fixed noise monitoring stations which are located in our neighboring communities.
Noise is measured by averaging out the noise levels during the day (a 16-hour day) during the summer period and is shown in decibels (dB). This averaging-out means that the day’s high and low levels are averaged out to give a single figure. This averaged decibel measurement is called ‘LAeq’, and it is the most common international measure of aircraft noise.
In the UK, government research indicates that people start being concerned by aircraft noise at 57dB LAeq.

Edinburgh Airport is a 24 hour operational airport. There are currently no restrictions on night flying. Night time is regarded as the period between 23:30 and 06:00.
To show the different noise levels around the airport we commisioned contour mapping from the CAA. Above is the noise contour map for the area around Edinburgh Airport. The contours are an irregular shape because you get more noise at the ends of the runway where planes take off and land.
To ensure that Airports provide consistent and consistant standards of contour mapping the CAA produced a document in early 2021 detailing the standards required for the production of noise contour mapping this is detailed within the attached CAP2091 Policy on Minimum standards for Noise Modelling
Edinburgh Airport follows the policy and procedures detailed in this document in the production of all our noise contour mapping .
