Benefits of Developing a Detailed Noise Model for a Large Industrial Site

The development of detailed noise models for large industrial sites is becoming increasingly common in New Zealand. However, there appears to be a dearth of information on the benefits of developing such a model. Based on a number of recent project experiences, we have found that the key benefits of developing a detailed noise model for a large industrial site include:&_bullet; Ability to identify and prioritise cost-effective noise control opportunities for an existing site;&_bullet; Accurate assessment of how future expansions may affect total site noise emissions;&_bullet; Inform the development of noise budgets for contract purposes and compliance with relevant environmental noise standards; and&_bullet; More effective communication with project team, site operators and general public through the use of model outputs such as noise contour maps.The aim of this paper is to consolidate recent project experiences that have involved detailed noise models and provide information on the benefits these models can offer for large industrial sites.
