6.3          Noise Modelling and Assumptions
A noise assessment of the proposed development was conducted as a 3D noise emission model using
SoundPLAN V9.0 with the following parameters and assumptions:
•    Elevation data of the surrounding area is taken from the Intergovernmental Committee on Surveying and
     Mapping Elevation and Depth (ELVIS) database.

•    Noise sources such as car door closure noise that are located internally do not require assessment as the
     building structure will provide significant shielding.

•    Building layouts as per site plans (Appendix A).

•    The Noosa Civic Village and existing Noosa Civic centre were both assessed together.

•    The onsite traffic generation rate (supplied by SLR Traffic) in the peak (1 hour) period was applied.

•    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.

•    Conversation noise was assumed from the nearest loading bay, car parking or driveway area to the
     receiver.

•    Conversation noise was based on a ‘male’ voice with ‘raised’ vocal effort as reported in published data
     contained in Harris, C.M., Handbook of Acoustical Measurements and Noise Control – 3rd ed. Ch 16.3,
     Mc Graw-Hill Inc, 1991. Noise duration was assumed to be continuous over the time period.
