ANNUAL COMPLIANCE REPORTING
Each year, Queenstown Airport prepares Annual Aircraft Noise Contours (CAANC), which show where noise from aircraft flying overhead averages 55 dB Ldn, 60 dB Ldn, and 65 dB Ldn over a year.
The contours indicate how aircraft noise at any time compares to the final noise boundary allowed for in the operative district plan. They also give homeowners in the noise areas an indication of when they are likely to receive offers of acoustic treatment. Noise mitigation will be offered when, or just before, the actual noise contour reaches a property. As aircraft movements gradually increase, more properties will become eligible for noise reduction funding.
