How are noise contours produced?

ERCD maintains and operates the official UK civil aircraft noise contour model, ANCON. ANCON takes data on aircraft movements, routes, noise generation and sound propagation to compute the noise exposure on the ground around an airport due to the aircraft operations. The noise generation and propagation algorithms used in ANCON accord with international best practice in noise modelling. ANCON and ERCD are recognised internationally as leaders in the field of noise modelling.
