| Research Abstract |
Research and development of numerical acoustical propagation simulation technologies of real-life areas were achieved using digital geographic information such as geographic information system data and airborne laser topographical scanning data, and remote sensing information. Techniques for geometry generation of the subject topography and buildings, grid generation and the estimation of surface acoustic characteristics were developed. The simulation code has been distributed-memory parallelized for large-scale computations. The simulation results have been validated by comparison with scale-model measurements.
