Noise Impact Assessment


4 Operational Noise Assessment
Noise prediction was undertaken using computer-aided modelling software SoundPLAN v8.2.
SoundPLAN is a well-established, industry-leading noise prediction program, recognised by
acoustic consultants, private companies, and government organisations globally.

All noise sources associated with the proposed development have been incorporated into the
noise prediction model. To predict noise emissions, SoundPLAN was programmed to use ISO
9613-2:1996 Acoustics - Attenuation of sound during propagation outdoors - Part 2: General
methods of calculation prediction methodology.

4.1 Noise Modelling Extents
The noise model extents include the noise sensitive buildings and ancillary structures that are
most exposed to the proposed development. The model incorporates all terrain within at least
500 m of the site.

4.2 Terrain
A terrain model based on light detection and ranging (LiDAR) was sourced from the Department
of Natural Resources, Mines and Energy (DNRME).

This bald earth digital elevation model (DEM) was created as part of the ‘Noosa-Gympie 2015
Project’. The dataset has a resolution of 1.0 m. The DEM was converted from a raster file format
to contour lines using QGIS v3.34. The contour lines were then imported into SoundPLAN as
elevation lines, allowing SoundPLAN’s triangulation algorithms to generate a digital ground model
(DGM).

4.3 Buildings and Structures
Buildings and structures were identified using a combination of aerial imagery (Queensland Globe
& Google Earth) and site visits. The buildings footprints were traced into the noise model from
Queensland Government high resolution aerial imagery. Carports and other similar structures
with no walls were omitted from the building footprint. Single story buildings were modelled at a
height of 4.0 m above natural earth, two-story buildings were modelled at a height of 6.0 m.
Industrial buildings were modelled at an assumed height of 7.5 m (unless specified on
architectural plans). Auxiliary buildings such as sheds were not included within the model.

4.4 Ground Absorption and Vegetation
Minimal areas of hard ground were digitised from high-resolution aerial imagery. Local roads and
car parks were modelled as acoustically ‘hard’ (i.e. reflective) and the remaining areas were
modelled as acoustically ‘soft’ (i.e. absorbent) throughout.

4.5 Existing Noise Protection Barriers
No noise protection barriers were included in the noise model for the purposes of a conservative
assessment.

4.6 Existing Fixed Mechanical Plant
Noise emissions from existing fixed mechanical plant have been assessed by Live It Acoustics
personnel. Attended noise measurements of site mechanical plant were conducted on 21 January
