*Receiver 1 comprises of dwellings located in Coral Tree Avenue. Receiver 2 is dwellings located in Wyandra
Street, and Receiver 3 is the proposed on-site residential building.


4.1.2      Sleep Disturbance
Sleep disturbance criterion levels are taken from the EPA Ecoaccess Guideline: Planning for Noise
Control (PNC). As a rule in planning for short-term or transient noise events, the indoor sound
pressure level should not exceed approximately 45 dB(A) Lmax more than 10-15 times per night.
The corresponding external noise level from the PNC, assuming partially closed windows, is 52
dB(A) Lmax, measured in the free field (4m from the façade of a building).


4.1.3      Mechanical Plant
Assessment of mechanical plant is pursuant to the noise requirements of EPP 2008 Background
Creep (steady-state) and potentially the EPA Ecoaccess Guideline: Planning for Noise Control.

The Ecoaccess Guideline: Planning for Noise Control recommends that a criterion is set based
upon background noise planning levels for the applicable receiver land use. Table 1 and Table 2 of
the guideline have been referred to in establishing the Ecoaccess criteria.

The design levels for both criteria are presented in Table 3 over page. To achieve a reasonable
balance between satisfying noise limits and the cost of achieving the noise limits, we recommend
that the EPP2008 Background Creep is a suitable criterion.
