In this paper, a comparison of parallel beam-tracing methods is presented and an original parallel domain decomposition method is proposed to solve numerical acoustic problems. A hybrid method between the ray-tracing and the beam-tracing method is first introduced. Then, classical parallelization methods are exposed and compared on shared and distributed memory architectures. Finally, a new parallel method based on domain decomposition principles is proposed. This method allows to handling large-scale problems better than other existing methods when taking into account the input/output and preprocessing steps. Parallel numerical experiments, carried out on a real world problem -namely the acoustic pollution analysis within a large city-illustrate the performance of this new domain decomposition method.
