项目摘要
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.
研究了基于波动方程的建筑环境大尺度声场计算机模拟技术,建立了典型声场的声场数据库。由于实际房间中声场的巨大性和复杂性,需要用于求解数学物理系统的高效计算技术。给出了适合于每种声场的数值求解器,包括适当的参数设置。本文还讨论了与形状建模和吸收建模有关的边界建模技术。构建的数据库由六种类型的十一个房间组成。在房间内测量脉冲响应,并将其包括在数据库中,以及其他信息,如CAD数据和照片。
