Following the above noise level measurements conducted 15 metres from the eastern end of the Allstar
Metal Fabrication building, source noise level measurements were also conducted from inside the
building, to gain an appreciation of the noise levels from metal fabrication. Noise sources included
radio, compressor, grinding, metal guillotine, welding and metal cut-off saw. Table 3 details the results
of these noise level measurements, which were typical for metal fabrication (3 workers), and Figure 3 is
a graphical presentation for the nominated parameters.
