| Research Abstract |
Computer simulation techniques based on the wave equation are investigated to analyze large-scale sound fields in built environments and a database of sound fields in typical sound fieldsis constructed. Due to the largeness as well as the complexness of the sound field in an actual room, highly efficient computational techniques for solving the math-physical system are required. Appropriate numerical solvers that suit for each sound field to be analyzed are given including the adequate parameter settings. The boundary modeling techniques are also discussed on the problems relating with shape modeling and with absorption modeling. The constructed database consists of six types with eleven rooms. Impulse responses are measured in the rooms and included into the database as well as the other information like CAD data and photographs.
