Annual aircraft noise contours

Annual aircraft noise contours

Auckland Airport prepares annual aircraft noise contours (AANCs), which show where noise from aircraft flying overhead averages, over a year, 60 dBA and 65 dBA. Over time the contours give the public an indication of how aircraft noise at any time compares to the ultimate noise the airport is permitted to make.

The contours will also give homeowners (and other activity sensitive to aircraft noise (ASAN) owners) in the noise areas an indication of when they are likely to receive an offer of acoustic treatment as outlined in the noise mitigation programme section.

The most recent set of AANCs were published in October 2009 and show where the noise contours are expected to be in October 2010. In this latest set of AANCs the Ldn 60 dBA and Ldn 65 dBA line is slightly wider and longer than the 2009 AANCs. Offers to owners relating to the 2010 AANCs will be made in April 2010. Auckland Airport will contact those eligible to be offered acoustic treatment.
