Abstract

Early blind individuals can localize single sound sources better than sighted participants, even under monaural conditions. Yet, in binaural listening, they struggle with understanding the distances between three different sounds. The latter ability has never been tested under monaural conditions. We investigated the performance of eight early blind and eight blindfolded healthy individuals in monaural and binaural listening during two audio-spatial tasks. In the localization task, a single sound was played in front of participants who needed to localize it properly. In the auditory bisection task, three consecutive sounds were played from different spatial positions, and participants reported which sound the second one was closer to. Only early blind individuals improved their performance in the monaural bisection, while no statistical difference was present for the localization task. We concluded that early blind individuals show superior ability in using spectral cues under monaural conditions.

早期失明个体的单耳听觉空间能力。
早期失明的人能比正常的人更好地定位单一声源,即使是在单一的条件下。然而,在双耳听力中,他们很难理解三种不同声音之间的距离。后一种能力从未在单一条件下测试过。我们研究了8名早期盲者和8名蒙眼健康者在两个音频空间任务中的单耳和双耳听力表现。在定位任务中,在需要正确定位的参与者面前播放一个声音。在听觉平分任务中,从不同的空间位置播放三个连续的声音,参与者报告第二个声音更接近哪个声音。只有早期失明的个体在单耳切分中的表现有所提高,而在定位任务中没有统计学差异。我们的结论是,早期失明个体在单声道条件下表现出更强的光谱线索使用能力。
