Auralizations can be computed in a variety of ways as well as be rendered over different sound reproduction systems. They are used as a design tool in architectural projects and for fundamental studies on spatial perception and cognition, hence requiring reliability and confidence in the obtained results. This study assessed this reliability through auditory perception stability by comparing the perceived differences between two rendering systems for a given set of second-order Ambisonic auralizations: virtual loudspeaker binaural rendering over head-tracked headphones versus 32-loudspeaker rendering. Anechoic extracts of jazz pieces have been recorded and presented in various acoustic conditions over these two systems, evaluated on the following criteria: Readability, distance, listener envelopment (LEV), apparent source width (ASW), reverberance, and loudness. Results show that consistent significant differences between scene conditions are comparably perceived across the two systems. However, significant effects of the sound reproduction system were observed for ASW, LEV, and reverberance in some configurations.
听觉化可以通过多种方式计算，并通过不同的声音再现系统呈现。它们被用作建筑项目的设计工具，以及用于空间感知和认知的基础研究，因此需要在获得的结果中具有可靠性和置信度。本研究通过比较给定的二阶 Ambisonic 听觉化的两种再现系统之间的感知差异，评估了这种听觉稳定性的可靠性：头部跟踪耳机上的虚拟扬声器双耳渲染与 32 扬声器渲染。已经录制了爵士乐曲目的无回声片段，并在这两个系统上呈现了各种声学条件，根据以下标准进行评估：可理解度、距离、听众包围感 (LEV)、表观声源宽度 (ASW)、混响和响度。结果表明，两个系统都能感知到场景条件之间一致的显著差异。然而，在某些配置中，声音再现系统对 ASW、LEV 和混响有显著影响。
