Provides guidance on the siting and construction of new buildings against aircraft noise intrusion and on the acoustical adequacy of existing buildings in areas near aerodromes. The assessment of potential aircraft noise exposure at a given site is based on the Australian Noise Exposure forecast (ANEF) system. The Standard also provides guidelines for determining the type of building construction necessary to provide a given noise reduction.
This Standard, together with the relevant Australian Noise Exposure Forecast (ANEF) chart or locality map available for the aerodrome under consideration, provides guidelines for determining—
(a) whether the extent of aircraft noise intrusion makes building sites ‘acceptable’, ‘unacceptable’ or ‘conditionally acceptable’ for the types of activity to be, or being, undertaken (Clause 2.3);
(b) for ‘conditionally acceptable’ sites, the extent of noise reduction required to provide acceptable noise levels indoors for the types of activity to be, or being, undertaken; and
(c) the type of building construction necessary to provide a given noise reduction, provided that external windows and doors are closed (see Note 1).
This Standard deals specifically with noise from take-off, landing and circuit training operations at civil aerodromes or military airfields.
The acceptability of outdoor spaces is not covered by this Standard.
1 The recommendations for building construction are based on the assumption that external windows and doors are shut. If external windows or doors are opened for ventilation or other purposes, the noise attenuation values for various components given in Clause 3.3 will not be achieved. Item (c) above implies that mechanical ventilation will need to be installed when external windows and doors are shut to provide adequate protection against aircraft noise intrusion. Whether or not sufficient ventilation can be achieved by mechanical or other means should be considered before the selection of building components described in Clause 3.3.
2 There may be a significant increase in costs incurred in buildings designed to provide higher than normal noise attenuation for their type.
Application of this Standard should be considered when a building site is located within certain distances from an aerodrome as given below. The following distances are approximations and should be used as guidelines only:
(a) Within 15 km of an international airport, major domestic airport, or major military aerodrome.
(b) Within 10 km of a domestic airport with regular scheduled public transport services.
(c) Within 5 km of any other type of aerodrome for which an ANEF chart is available. Reference to the appropriate ANEF chart will be necessary to determine the applicability of the recommendations of this Standard.
Section 2 of this Standard gives guidelines for determining the acoustical acceptability of a particular site.
Section 3, used in sequence with Section 2, gives guidelines for determining the extent of noise reduction and type(s) of construction required for a particular building.
A high level of skill is required to comply with many of the provisions of this Standard. Unsuccessful designs may be difficult and expensive to remedy. Inferior aircraft noise attenuation performance resulting from unsatisfactory design and construction will detract from the value and usefulness of a building throughout its life. It is expected that the provisions of this Standard will be interpreted by a qualified acoustician experienced in the characteristics of aircraft noise.
