Assessment of noise to be expected at machine workstations using simulation techniques of geometric acoustics

Abstract:
The calculation of sound propagation in rooms using geometric acoustics methods is a proven and frequently used procedure for ensuring good acoustic environmental conditions in workplaces. Practical examples are used to show that it is also possible to predict the noise exposure levels to be expected at the operator stations of more complex machines that are not to be regarded as point sound sources, if certain techniques relating to data organization are incorporated. This makes it possible for a machine manufacturer to realistically estimate the noise exposure to be expected in this individual case once a data model has been created with the corresponding parameterized emission values for any given installation. The effect that can be achieved by additional noise reduction measures is shown in order to evaluate the analysis of the noise components arriving at a workplace.
