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.

听觉稳定性评估，比较动态虚拟音乐会听觉的双耳和扬声器Ambisonic演示

可以通过多种方式来计算听觉化，并在不同的声音再现系统上进行渲染。它们被用作建筑项目中的设计工具，以及用于空间感知和认知的基础研究，因此需要对所获得结果的可靠性和信心。这项研究通过比较给定的二阶Ambisonic听觉化的两个渲染系统之间的感知差异，通过听觉感知稳定性来评估这种可靠性：头戴式耳机的虚拟扬声器双耳渲染与32扬声器渲染。已记录并在这两种系统的各种声学条件下呈现了爵士乐的消声提取物，并根据以下标准进行了评估：可读性，距离，听者包围度（LEV），视在信号源宽度（ASW），混响和响度。结果表明，在两个系统之间，场景条件之间始终存在着明显的差异。但是，在某些配置中，对于ASW，LEV和混响，可以观察到声音再现系统的显着效果。
