RFI - 7. Accoustic
8. Environmental Assessment
8.1 Onsite Activities to Offsite Receivers
Noise associated with the development was assessed based on previous measurements of similar
activities. The calculations assume that the nominated activities are located at a representative.
distance within the development site to each receiver location. Any relevant shielding or building
transmission loss is taken into account for these activities.
8.1.1 Acoustic Quality Objectives
The noise source levels and predicted impacts at the receiver locations are shown in Table 9.
