Abstract

Objectives: The study aimed to examine the contribution of the position of a sound source to static postural control. The authors hypothesized that in line with the auditory anchorage theory, more benefits would be observed when sounds are positioned in easy-to-localize locations.

Design: A force plate was used to measure sway area, sway velocity, and standard deviation in 23 participants. Auditory stimuli were presented at various azimuth angles (0°, 45°, 90°), and their effects were compared with a silent baseline condition without any added auditory input.

Results: The present results revealed a significant improvement in sway parameters when auditory inputs were added. However, in contrast to the 0° and 45° locations, the 90° location did not affect sway area and SD when compared with the condition without auditory input. Improvement was observed across all the locations of the auditory inputs for sway velocity.

Conclusion: These findings support the auditory anchorage theory, suggesting that auditory objects positioned in areas that are easy to localize contribute more effectively to postural stabilization.

空间位置调节听觉输入对姿势控制的益处。

目的：本研究旨在探讨声源的位置对静态姿势控制的贡献。作者假设，根据听觉锚定理论，当声音被定位在容易定位的位置时，会观察到更多的好处。设计：用测力板测量23名受试者的摇摆面积、摇摆速度和标准差。以不同的方位角（0°，45°，90°）呈现听觉刺激，并将其效果与没有任何额外听觉输入的沉默基线条件进行比较。结果：本研究结果显示，当加入听觉输入时，摇摆参数有显著改善。然而，与0°和45°位置相比，与没有听觉输入的情况相比，90°位置对摇摆面积和SD没有影响。在摇摆速度的听觉输入的所有位置都观察到改善。结论：这些发现支持了听觉锚定理论，表明放置在易于定位区域的听觉物体更有效地促进了姿势稳定。

期刊介绍： From the basic science of hearing and balance disorders to auditory electrophysiology to amplification and the psychological factors of hearing loss, Ear and Hearing covers all aspects of auditory and vestibular disorders. This multidisciplinary journal consolidates the various factors that contribute to identification, remediation, and audiologic and vestibular rehabilitation. It is the one journal that serves the diverse interest of all members of this professional community -- otologists, audiologists, educators, and to those involved in the design, manufacture, and distribution of amplification systems. The original articles published in the journal focus on assessment, diagnosis, and management of auditory and vestibular disorders.
