The NHMRC Centres of Research Excellence (CRE) in Air Quality and Neurosleep based at the Woolcock Institute held an all day symposium on noise and health with a range of local and international speakers including Anna Hansell from Imperial College, London and Irene Van Kamp from the National Institute for Public Health and the Environment, Netherlands. Current guidelines on assessing the health impact of noise were discussed as well as a discussion on the type and value of future research including an assessment of the impact of a second Sydney Airport. The need for better measurement, not only of noise, but health outcomes was recognised. The lack of quality research was also raised and one of the aims of the symposia was allow better networking of researchers and allow potential formation of a team approach to new studies. The NHMRC CREs have already been approached by government bodies attending the symposia to potentially undertake research.
