Abstract Although spatial hearing is of great importance in everyday life, today’s routine audiological test batteries and static test setups assess sound localization, discrimination and tracking abilities rudimentarily and thus provide only a limited interpretation of treatment outcomes regarding spatial hearing performance. To address this limitation, we designed a dynamic sound field test setup and evaluated the sound localization, discrimination and tracking performance of 12 normal-hearing subjects. During testing, participants provided feedback either through a touchpad or through eye tracking. In addition, the influence of head movement on sound-tracking performance was investigated. Our results show that tracking and discrimination performance was significantly better in the frontal azimuth than in the rear azimuth. Particularly good performance was observed across the rear midline in localization, discrimination and tracking tests. As expected, free head movement improved sound-tracking abilities. Furthermore, feedback via gaze detection led to larger tracking errors than feedback via the touchpad. We found statistically significant correlations between the static and dynamic tests, which favor the snapshot theory for auditory motion perception.

动态声场测听：全水平面静态和动态空间听力测试

摘要 虽然空间听力在日常生活中非常重要，但今天的常规听力测试电池和静态测试装置基本评估声音定位、辨别和跟踪能力，因此只能对有关空间听力性能的治疗结果提供有限的解释。为了解决这个限制，我们设计了一个动态声场测试装置，并评估了 12 名听力正常的受试者的声音定位、辨别和跟踪性能。在测试期间，参与者通过触摸板或眼动追踪提供反馈。此外，还研究了头部运动对声音跟踪性能的影响。我们的结果表明，正面方位角的跟踪和辨别性能明显优于背面方位角。在定位、辨别和跟踪测试中，整个后中线都观察到了特别好的表现。正如预期的那样，自由头部运动提高了声音跟踪能力。此外，通过凝视检测的反馈比通过触摸板的反馈导致更大的跟踪误差。我们发现静态和动态测试之间存在统计学上显着的相关性，这有利于听觉运动感知的快照理论。
