8.3 Offsite Activities to Onsite Receivers
During site investigation, offsite activities were not audible at the proposed development due to
screening of the building and road traffic noise, therefore modelling of offsite activities were
undertaken to account for potential impacts of the surrounding commercial and retail. Table 16
presents the predicted noise impacts from the nearest commercial premise to the proposed
development. The predicted noise impacts of the offsite activities are compared against the internal
noise requirements of the EPP Acoustic Quality Objectives as shown in Table 12.
