At this point the method employed by MENCO departs from most other companies doing noise studies, as we model (using the appropriate software and stipulated methods) the various impacts that could be expected due to various activities during the construction, operational and even closure phases. This data is represented as isopleths of constant noise levels in various formats as seen in Figure 2. Apart from the impact that the activity(ies) may have on the surrounding environment, we also investigate issues such as the future (predicted) total noise levels, allowing the quantification of unacceptably high noises (as stipulated by local ordinances) and changes that receptors may experience (SANS 10103:2008), directly relating to the proposed activity/ development.
