针对虚拟声学环境（VAE）的感知评估，引入“合理性”作为质量标准，对于虚拟声学中的许多应用都有价值。我们提出了一个定义以及合理性的实验操作，指的是与听众对相应真实声学事件的期望的感知一致性。测量模型包括通过在是/否测试范式中对相应的真实和模拟刺激进行评级并根据信号检测理论分析结果来对与这种非明确的内部参考的偏差进行无标准评估。最小效应假设的规范允许以任何所需的严格性测试合理性。该方法通过对两个不同开发阶段的动态双耳合成系统的感知评估进行了演示。
Aiming at the perceptual evaluation of virtual acoustic environments (VAEs), 'plausibility' is introduced as a quality criterion that can be of value for many applications in virtual acoustics. We suggest a definition as well as an experimental operationalization for plausibility, referring to the perceived agreement with the listener's expectation towards a corresponding real acoustic event. The measurement model includes the criterion-free assessment of the deviation from this non-explicit, inner reference by rating corresponding real and simulated stimuli in a Yes/No test paradigm and analyzing the results according to signal detection theory. The specification of a minimum effect hypothesis allows testing of plausibility with any desired strictness. The approach is demonstrated with the perceptual evaluation of a system for dynamic binaural synthesis in two different development stages.
