Abstract

Estimates of exposure to aircraft noise are generally based on an average day of operations and residential population figures. While providing a convenient way to condense information, this does not reflect noise experiences across the day. This paper details an approach to inject more reality into exposure assessments, using disaggregate geographic information systems-based flight movement data and a procedure to track the population over the day. Using empirical evidence from Sydney, this leads to markedly different insights about noise impacts, which in turn has ramifications for policy-makers planning flight operations and residential settlement patterns in impacted areas.
