Reliability of Sound Field Simulations
Languages of publication
One of the most important questions in sound field modelling is connected with the reliability of results. The absolute accuracy of values predicted by the software is very difficult to quantify because of an uncertainty in the measurements. But it is possible to determine an influence of the input data accuracy and calculation parameters on the obtained results. Problems and differences in the sound field simulation results are presented in the hereby paper. Test procedures of the sound filed simulation software and also well-documented exemplary objects in an open space will be the main aim of investigations.
