    Advanced distributed memory parallel computers such as supercomputers and the like are spreading. Based on this background, development of a large-scale non-stationary analysis method for the evaluation of acoustic characteristics comprehensively, a frequency response of acoustic instruments such as speakers, and directional characteristics has been required.

     Therefore, in this research, we will research and develop large-scale acoustic analysis method based on the time-domain parallel finite element method.

     We apply the iterative domain decomposition method as an effective parallelization method for large-scale analyses based on the finite element method, and we show its effectiveness in a large-scale acoustic analysis.

     The developed non-stationary numerical acoustic analysis code has been shown to be applicable to sufficient reproduction of non-stationary acoustic phenomena and an acoustic environment analysis of live houses of tens of millions of elements, we found it to be an acoustic analysis method, so we will report it.
