New Zealand Acoustics, 18(3), pp.9- 19 . (2005).

This abbreviated paper describes the context and background to a planning proposal to achieve minimum indoor acoustic exposure levels in new dwellings in the Central Area of Wellington City. The proposed method to be adopted is to specify acoustic insulation based on a minimum acoustic performance of the building envelope. This report sets out to assess and qualitatively comment on the proposed measures in both acoustic terms and in terms of “process” under the Resource Management Act 1991.
