AS 3671-1989

Sets out guidelines for determining the acceptability of indoor and outdoor spaces for specific activities in the presence of road traffic noise, and the extent of noise reduction or type of construction that might be needed to make such spaces acceptable. Also sets out guidelines for determining the acoustical adequacy of existing buildings near routes carrying more than 2000 vehicles per day.

This Standard concerns the reduction of road traffic noise intrusion in buildings in areas near new or upgraded freeways, tollways, major roads, and national routes or other roads carrying more than 2000 vehicles per day; it may also be used to assess the acoustical adequacy of existing buildings in similar areas. It provides guidelines for determining the type of building construction necessary to achieve acceptable noise levels indoors, as recommended in AS 2107, for different types of activity.NOTES:1. In cases where the required sound transmission losses of building components as calculated according to this Standard exceed those given in Appendix B, a special type of construction and design may be necessary to obtain an acceptable acoustic environment inside the building. Such buildings fall outside the scope of this Standard and specialist acoustic advice should always be obtained.2. An example of the application of this Standard is given in Appendix D.
