6.2          Noise Source Levels
Table 6 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.

Function noise emissions are assessed in Sections 6.5.

6.3          Calculation Assumptions
The following assumptions have been made for noise calculations:

•    Outdoor dining was predicted from the nearest outdoor dining area. The noise duration was assumed to
     be continuous during the assessment time period. The sound level includes allowance for low-level
     background amplified music.

•    Crowd noise was based on data contained in paper ‘Prediction of Noise from Small to Medium Sized
     Crowds’ Hayne et al, 2011. Duration was assumed to occur continuously during the assessment period.

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

•    Bus movements were predicted from the bus turn around area.

•    Attenuation from building screening was included where applicable.

•    Noise attenuation of 7dB through an open window at a receiver was applied for internal predictions. It is
     noted that between 15 and 20dB could be expected to be achieved through a closed window or door.

•    Noise source locations on Level 4 are shown in Figure 5.
