NZS 6806:2010
Acoustics - Road-traffic noise - New and altered roads
Sets out procedures and requirements for the prediction, measurement, and assessment of road traffic noise for new and substantially altered state highways and local roads. The Standard is intended to be used primarily by local authorities and road controlling authorities and seeks to promote quicker and consistent decision-making nationally regarding the management of road traffic noise. It also provides best practice guidance and advice on methods for mitigating reverse sensitivity situations and the environmental effects of noise exposure on nearby noise-sensitive activities. For the purpose of this Standard, where any project includes a mixture of new and upgraded existing roads the roading authority shall determine the relevant criteria to be applied to each section of the road for traffic noise mitigation.
