    AIRCRAFT NOISE INSULATION FORRESIDENTIAL DEVELOPMENT IN THE VICINITY OF PERTH AIRPORT

    Perth Airport is fundamental to the continued development of the Perth Metropolitan Region and theState as a whole. Investment in airport infrastructure and the economic opportunities associated withthe operation of the airport are now recognized as an important, and perhaps critical element in theprosperity of a city such as Perth.

    Accordingly, the airport and its ongoing development need to be recognized in the planning of theregion, and its operation protected as far as practicable from development with the potential toprejudice its performance. One of the main issues to be addressed in the planning of areas in thevicinity of the airport is aircraft noise, which is the focus of the Western Australian PlanningCommissions Statement of Planning Policy No. 5.1 - Land Use Planning in the Vicinity of PerthAirport.

    There are a number of existing built-up areas in the vicinity of the airport which are already affectedby significant levels of aircraft noise, and the extent of affected areas is likely to expand in the futureas a consequence of the growth in air traffic and the development of new runway facilities. Thechallenge in planning for these areas is to manage the impact of aircraft noise, taking into account theinterests of existing communities and the needs of a growing metropolitan region.

    In response to this challenge, Statement of Planning Policy No. 5.1 - Land Use Planning in the Vicinityof Perth Airport, proposes that noise insulation be required as a condition of local governmentplanning approval, for all new residential development above the 25 ANEF noise exposure contour.Where practicable, the standard of insulation required is to be based on the achievement of indoordesign sound levels recommended for the particular building type or activity in AS 2021.

    This report is the first of its kind in Australia. It contains recommendations regarding deemed-to-comply noise insulation measures to achieve the indoor design sound levels recommended within AS2021. An alternative approach would be to engage an acoustic engineer to recommend and certifynoise control measures for the building in question to achieve the relevant indoor design sound levelsrecommended by AS 2021.
