Noise Assessment
Brett Williams
Scope• The measurement of the existing ambient
noise (day and night time).• A noise study of the future impact during
construction and operation of the proposed desalination plant, taking into consideration sensitive receptors.
• Noise impacts associated with construction of the power line on sensitive receptors.
Methodology
• SANS 10103:2008 Version 6 - The measurement and rating of environmental noise with respect to annoyance and to speech communication.
• SANS 10328, Methods for environmental noise impact assessments.
• SANS 10357, The calculation of sound propagation by the Concawe method.
Outputs
• Prediction of the extent of the noise emitted from the plant
• Recommendations to mitigate the noise pollution
Inputs
• Legislation• Identification of sensitive locations• Layout of site• Inventory of buildings and associated equipment • Expected traffic • Work times• Weather data• Topographical data
