Traditionally gathering noise levels and exposure duration data from the various tasks and processes is carried out in workplaces, and then that data is used to calculate total exposure. This results in a large amount of data and detail that, while accurate, is prone to uncertainties.
Noise exposure data was gathered during visits to selected South Australian workplaces with the aim of finding out how the data could be used to construct typical noise exposure profiles of workers at those sites. These profiles would then be explored for successful methods of gathering workplace noise exposure data that can be used to construct a national noise exposure data base.
A simplified methodology for small, medium and large workplaces was outlined that may introduce some degree of uncertainty; with practice and experience, reasonably representative noise exposure data should be able to be conveniently gathered when inspectors are visiting work sites. This data would then be suitable to entered into a National Noise Exposure data base.
