可以使用多种可选的声学建模方法来合成任意封闭空间的房间脉冲响应(RIR)，每种方法都具有其特定的优点和局限性。本文致力于从基于波和几何声学的方法中获得混合RIR，优化以跨时间或频率的不同区域使用。考虑了如何在幅度和边界行为方面跨建模域匹配这样的RIR，并使用一些标准化的案例研究来验证该方法。
Synthesizing the room impulse response (RIR) of an arbitrary enclosure may be performed using a number of alternative acoustic modeling methods, each with their own particular advantages and limitations. This article is concerned with obtaining a hybrid RIR derived from both wave and geometric-acoustics based methods, optimized for use across different regions of time or frequency. Consideration is given to how such RIRs can be matched across modeling domains in terms of both amplitude and boundary behavior and the approach is verified using a number of standardised case studies.
