“…It is clear that the phenomenon is a result of the interaction of visual and vestibular information which is comparable to that in the oculogravic illusion (Graybiel & Clark, 1965) and the interaction of auditory and vestibular information with the audiogyral illusion (Clark & Graybiel, 1949). But what are the primary causes of the illusion?…”

The purpose of this study was to compare the sensitivity of humans to angular accelerati on using the perception of rotation and the perception of the oculogyral illusion as two indicators. Ten men with normal vestibular function were studied in a precision rotation device using a random, forced choice, double staircase method to determine the thresholds. The thresholds for the oculogyral illusion were found to be substantially and significantly lower than thresholds for the perception of rotation. The implications of these findings for an understanding of the oculogyral illusion are discussed.

“…A similar difference has been reported related to ''audiogyral illusion [9][10][11][12].'' Some studies examining the influence of rotary acceleration on auditory localization revealed that the perceived position of a sound source shifted in the opposite direction of acceleration [9][10][11][12]. In contrast, other studies showed that the sound source shifted in the direction of acceleration [13,14].…”

This study investigated how auditory space is represented during linear self-motion. Results of several studies suggest that whether the listener's motion is active or passive affects sound localization. Therefore, we investigated whether the style of the self-motion affects the perceived auditory space. As the passive condition, observers were transported automatically forward by a robotic wheelchair. In contrast, observers controlled the movement of the robotic wheelchair or walked straight ahead in active conditions. The observers indicated the direction in which the sound was perceived relative to their coronal plane (i.e., a two-alternative forced-choice task). The results of experiments demonstrated that the sound position aligned with the subjective coronal plane was displaced backward relative to the observers' physical coronal plane both in active and passive motion conditions. These results suggest that perceived self-motion itself affects auditory space representation irrespective of the intention of the movement.

“…A basic auditory processing effect that is independent of beat perception also explains the results. It is known that vestibular input can change how any particular sound is heard (Clark 1949;Graybiel 1951). The sound waves reaching the ear drums may be identical for two situations; one where there is vestibular input from head movement and another situation where the head is still, but sound perception is different for the two situations.…”

A Simpler Explanation for Vestibular Influence on Beat Perception: No Specialized Unit Needed

Empirical Musicology Review

Some researchers have hypothesized the existence of a specialized brain unit for beat perception in music which is directly influenced by vestibular stimulation arising from motion. They also suggest that the unit is involved in the entrainment of movement to music. However, the data used to support this hypothesis may be explained by a simpler phenomenon: the audiogravic and audiogyral effect. This effect is not related to beat perception at all but deals with perceived sound changes under accelerations. If the perception of a sound changes as a consequence of acceleration of the vestibular system, and those accelerations are timed to coincide with particular beats in a stream of unaccented beats, then those beats will actually sound different. The detection of a given meter in that unaccented stream will therefore arise from this change in sound processing, with no need for a specialized brain mechanism for beat perception. There is no direct evidence supporting the existence of an innate brain unit.
