Managing aircraft noise is a complex issue. Passengers want shorter flights, pilots want easier access to airports and airlines want reduced levels of fuel consumption and greenhouse gas emissions. All of these factors are important when considering how to reduce aircraft noise.

The impact of aircraft noise cannot be underestimated. While to some people it may be barely noticeable, to others the impact ranges from different levels of annoyance to a real, measurable effect on health and life style. One way to gain a better understanding of the impacts of aircraft noise is through access to comprehensive, clear and up-to-date noise information around airports and under flight paths.

How noise monitoring is undertaken

Permanent noise monitoring is undertaken at nine airports. Information gathered includes the identity, flight path and altitude of each aircraft operating to and from the airport, the noise levels produced by individual aircraft and general background noise. This information is collected 24-hours-a-day, seven-days-a-week by fixed noise monitors located as close to flight paths as possible. In addition, there is a program of short-term monitoring at other locations, including smaller, general aviation airports.

What noise monitoring information is used for

Noise information is used for a variety of different purposes such as, determining the contribution of aircraft to overall noise exposure, assessing noise levels from aircraft, assisting in the planning of airspace use and help in future planning of development on areas around an airport.

Noise monitoring also enables aircraft noise information to be provided to government, industry organisations, community groups and individuals.
