Using the methods as recommended by DEAT, we determine the significance of impacts due to noise from the various activities for each phase (construction, operational and closure phases), whether the activity(ies) takes place at night or day. Due to the methodology employed, the impact assessment automatically considers cumulative impacts due to other project activities, as well as the pre-project ambient sound levels. This allows the accurate determination of components such as magnitude (intensity) and spatial extent, that, together with field work (assisting with the determination of probabilities) and project information (duration of activity), defining the impact significance. See also Table 2.
