将用于光传播的辐射度算法加以改进，以获取对应于某一频率的厅堂脉冲响应，并针对建筑材料的声发射特性，通过快速傅立叶变换后在频域合成，对建筑厅堂的传递特性进行仿真，为在设计阶段得到诸如清晰度、早期延迟时间等厅堂的声学评价指标提供了一种有效的途径。
The radiometric algorithm used for light propagation was modified to obtain the impulse response of the hall corresponding to a certain frequency, and the acoustic emission characteristics of building materials were synthesized in the frequency domain by means of fast Fourier transform, and the transfer characteristics of the building hall were performed. Simulation provides an effective way to obtain acoustic evaluation indicators such as clarity and early delay time in the design stage.
