6.2          Noise Source Levels
Table 11 presents the typical noise sources associated with the development with the potential to impact
the nearest noise sensitive receivers. The noise source levels were calculated to one metre and include
corrections for tonality and impulsiveness as per AS1055. The number of events was estimated for a ‘peak’
one-hour time period providing a ‘worst case scenario’ applied to all time periods.

Outdoor entertainment area noise emissions are assessed in Section 6.5.

6.3          Calculation Assumptions
The following assumptions have been made for noise calculations:
•    The onsite traffic generation rate (supplied by SLR Traffic) in the peak (1 hour) period was applied. Car
     movements were considered at the nearest car parking or driveway area to the receiver. Car door
     closures and engine starts were predicted from the nearest group of car parking spaces relative to the
     receiver.

•    The method of predicting vehicle noise from the nearest single location is conservative as the noise
     sources would be spread out across the car park at varying distances from the receiver.

•    The onsite heavy vehicle generation rate in a peak (1 hour) period was based on a maximum 2 deliveries
     per hour per loading bay (18 per hour total). Deliveries were assumed to be 50% refrigerated.

•    Waste collection was assumed as a maximum of 2 collections per hour per loading area (4 per hour).

•    Truck deliveries and waste collection were predicted from the nearest loading bay and include all
     activities associated with loading and unloading.
