6.1 Metropolitan Colliery Noise Model Establishment Procedure The Metropolitan Colliery computer model was developed for the PRP 12 Study to incorporate the significant noise sources associated with the surface facilities. Additionally, surrounding terrain, aspects of the built environment and nearby receiver areas were also included in the model. The Metropolitan Colliery computer model was prepared using the SoundPLAN noise model utilising the CONCAWE algorithm, a commercial software system developed by Braunstein & Berndt International. The acoustical algorithms utilised by this software are endorsed national or international standards and are therefore accepted by the NSW DECC as suitable for use. 6.2 PRP 12 Fixed Plant Noise Audit - Sound Power Levels In order to establish the Metropolitan Colliery noise model, on-site nearfield noise measurements to determine fixed plant sound power levels (SWLs) were conducted on 13 and 22 November 2007. Noise measurement procedures were guided by the requirements of AS 1217.7-1985 “Acoustics - Determination of Sound Power Levels Part 7 Survey Method” (AS 1217.7:1985) and the results summarised in Table 16. These fixed plant SWLs have been utilised in the Project noise model, where relevant.
