We introduce an A-weighting variance measurement, an objective estimation of the sound quality generated by geometric acoustic methods. Unlike the previous measurement, which applies to the impulse response, our measurement establishes the relationship between the impulse response and the auralized sound that the user hears. We also develop interactive methods to evaluate the measurement at run time and an adaptive algorithm that balances quality and performance based on the measurement. Experiments show that our method is more efficient in a wide variety of scene geometry, input sound, reverberation, and path tracing strategies.

基于A加权方差测度的自适应几何声音传播

我们引入了A加权方差测量，即通过几何声学方法产生的声音质量的客观估计。与先前适用于脉冲响应的测量不同，我们的测量建立了脉冲响应与用户听到的听觉声音之间的关系。我们还开发了交互式方法以在运行时评估测量结果，并开发了一种自适应算法，可以根据测量结果平衡质量和性能。实验表明，我们的方法在各种场景几何，输入声音，混响和路径跟踪策略中更有效。
