姿势控制被认为是中枢神经系统整合和处理各种感觉输入的结果。在各种传入输入中，关于听觉信息在姿势调节中的作用的研究相对较少，导致结果相互矛盾。本研究的目的是探讨由沉浸式三维声音空间化系统传递的旋转听觉刺激对年轻受试者站立姿势的影响。20名被蒙住眼睛的直立受试者用一个力平台记录了他们的姿势摇摆。使用不同的声源旋转速度，然后突然将声音固定，并与两种控制条件进行比较：没有声音和静止声源。实验表明，与对照条件相比，受试者在旋转声音存在下的身体摆动幅度和速度有所降低。声源旋转得越快，受试者身体摇摆的减少就越大。此外，一旦声源被固定，就会观察到受试者姿势调节的中断。这些结果表明，听觉信息在姿势控制中是不可忽视的，它是影响姿势调节的附加信息。
Postural control is known to be the result of the integration and processing of various sensory inputs by the central nervous system. Among the various afferent inputs, the role of auditory information in postural regulation has been addressed in relatively few studies, which led to conflicting results. The purpose of the present study was to investigate the influence of a rotating auditory stimulus, delivered by an immersive 3D sound spatialization system, on the standing posture of young subjects. The postural sway of 20 upright, blindfolded subjects was recorded using a force platform. Use of various sound source rotation velocities followed by sudden immobilization of the sound was compared with two control conditions: no sound and a stationary sound source. The experiment showed that subjects reduced their body sway amplitude and velocity in the presence of rotating sound compared with the control conditions. The faster the sound source was rotating, the greater the reduction in subject body sway. Moreover, disruption of subject postural regulation was observed as soon as the sound source was immobilized. These results suggest that auditory information cannot be neglected in postural control and that it acts as additional information influencing postural regulation.
