论文摘要
在开发虚拟声学环境时，重要的是要了解计算成本与所得数值误差的感知意义之间的关系。在本文中，我们提出了一个质量标准，该标准评估了基于路径跟踪的声音传播模拟器的错误意义。我们提出了一个估计误差信号功率谱的分析公式。通过此频谱估计，我们可以使用修改后的Zwicker的响度模型来计算理想输出掩盖的误差信号的相对响度。我们的实验结果表明，提出的标准可以解释人类对各种情况下模拟误差的看法。
In developing virtual acoustic environments, it is important to understand the relationship between the computation cost and the perceptual significance of the resultant numerical error. In this paper, we propose a quality criterion that evaluates the error significance of path-tracing-based sound propagation simulators. We present an analytical formula that estimates the error signal power spectrum. With this spectrum estimation, we can use a modified Zwicker's loudness model to calculate the relative loudness of the error signal masked by the ideal output. Our experimental results show that the proposed criterion can explain the human perception of simulation error in a variety of cases.
