Bill Wood is a Consultant with the Wellington office, specialising in traffic noise and environmental noise control.

Bill's experience includes over 20 years researching, assessing and advising on the environmental effects of transport, especially road traffic noise. Prior employment at Opus International Consultants Central Laboratories in Gracefield, Lower Hutt included research evaluating the validity of Transit New Zealand traffic noise guidelines for low noise areas; evaluation of CRTN, CETUR, NORDIC and FHWA Traffic Noise Prediction Models for NZ application; and investigation into the noise and safety properties of various types of road surface and the longevity of effects of any noise reductions. He has also been involved in research into the effects of traffic noise on the community. The results of this research has contributed to the current draft New Zealand Standard DZ6806/V1.14 Acoustics-Road traffic noise-New and altered roads.

His experience includes attendance of a Noise and Vibration Control Course at Monash University, a Sound Insulation Course at Auckland University, the study of literature, presentation of papers and attendance at conferences and seminars, undertaking research projects into road traffic noise, and undertaking a number of studies into road traffic noise associated with projects. Additionally he has appeared as an expert witness at several resource consent hearings associated with new roads. More recently he has also appeared as an expert witness at several resource consent hearings associated with childcare centres, industrial noise projects, and windfarms.

Originally from Nelson, Bill first joined Marshall Day Acoustics' Wellington office in 2004.  Since then, Bill has gained a diversity of experience in acoustics consultancy and has developed skills in many project sectors including building acoustics, mechanical services noise control and environmental noise modelling and measurement.
