Maintaining postural stability requires the integration of multisensory information, including visual, vestibular, and somatosensory inputs. This study aimed to investigate the effects of narrowband noise across different frequency bands on static postural balance and cortical activation in healthy adults.

Discussion
Signed responses from readers of the wire.
Findings are preliminary and mechanistic; no actionable change to audiology or vestibular rehabilitation practice is warranted at this time.
Understanding how auditory stimuli interact with the multisensory balance system could eventually inform sound-based adjuncts to vestibular rehabilitation.
- 01fNIRS was used to measure cortical activation during exposure to frequency-labeled narrowband noise.
- 02Narrowband noise affected postural stability, suggesting cross-modal sensory integration effects.
- 03Study highlights the auditory system's role in multisensory balance control.
- 04Findings are mechanistic and exploratory in nature.
- 05Potential future relevance to vestibular rehabilitation research.
