“…Directionality of a moving sound source alone does not seem to matter in reducing sway; clockwise and counterclockwise moving auditory stimuli reduce postural sway variability (Tanaka et al 2001). However, sound that moves from the front toward the back of participants can result in participants leaning toward the approaching sound (Agaeva et al 2006), which helps explain why Soames and Raper reported a destabilizing effect of a sound stimulus that jumped between speakers anterior and posterior to participants (Soames and Raper 1992). In the current study, we used headphones to eliminate the possibility of the noise stimulus indicating a single fixed or moving location.…”

“…The existing research supports the idea that balance control can incorporate auditory information (Ross & Balasubramaniam, 2015; Dozza, Horak, & Chiari, 2007; Hegeman, Honegger, Kupper, & Allum, 2005; Tanaka, Kojima, Takeda, Ino, & Ifukube, 2001). However, there is no consensus on which types of sounds reduce sway (Ross & Balasubramaniam, 2015; Dozza et al, 2007; Hegeman, Honegger, Kupper, & Allum, 2005; Tanaka et al, 2001) and which increase sway (Agaeva, Al’tman, Kirillova, 2006; Soames & Raper, 1992). It is clear that balance control mechanisms can use auditory information including multisensory compensation and a dynamically changing sensory strategy (Dozza et al, 2007; Forti, Filipponi, Di Berardino, Barozzi, & Cesarani, 2010).…”

Timescales of postural fluctuation reflect underlying neuromuscular processes in balance control that are influenced by sensory information and the performance of concurrent cognitive and motor tasks. An open question is how postural fluctuations entrain to complex environmental rhythms, such as in music, which also vary on multiple timescales. Musical groove describes the property of music that encourages auditory-motor synchronization and is used to study voluntary motor entrainment to rhythmic sounds. The influence of groove on balance control mechanisms remains unexplored. We recorded fluctuations in center of pressure (CoP) of standing participants (N = 40) listening to low and high groove music and during quiet stance. We found an effect of musical groove on radial sway variability, with the least amount of variability in the high groove condition. In addition, we observed that groove influenced postural sway entrainment at various temporal scales. For example, with increasing levels of groove, we observed more entrainment to shorter, local timescale rhythmic musical occurrences. In contrast, we observed more entrainment to longer, global timescale features of the music, such as periodicity, with decreasing levels of groove. Finally, musical experience influenced the amount of postural variability and entrainment at local and global timescales. We conclude that groove in music and musical experience can influence the neural mechanisms that govern balance control, and discuss implications of our findings in terms of multiscale sensorimotor coupling.

“…On the other hand, it is well known that dynamic changes in sound, such as sound image movements, may influence human posture [36][37][38][39][40][41][42][43]. Certain kinds of sound movements evoke human body movements, a phenomenon that has occasionally been called "auditory kinesthesis."…”

Obstacle perception using sound is the ability to detect silent objects, such as walls and poles. It is very important for blind people to recognize their environment using acoustic information through their auditory sense when walking or conducting various daily activities. In this paper, to develop an objective method for evaluating the degree of obstacle perception acquisition in the education and rehabilitation of the blind, the authors measured the spontaneous body movements evoked by the approach of an acoustic virtual wall. Ten blind persons who have experienced obstacle perception in their daily life, and seven sighted persons with no such experience participated in the experiment. The reciprocal (approach and receding) movements of the virtual wall were presented using simulated reflected sound, and the spontaneous body movements of the subjects were measured. As the results indicate, eight of the ten blind participants showed large maximum values for the correlation function between the wall and their body movements, whereas six of the seven sighted participants showed small maximum values. These results indicate that body movements can be used for an objective evaluation of obstacle perception. In particular, it was determined that the maximum value of the correlation function is the most appropriate for such an evaluation, because it does not depend on the subject’s physique.
