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
