Stabilising Sound: A Perceptual Audio Framework for Balance Support Inspired by Vestibular Stimulation

This note outlines a proposal for a perceptual audio system that may help stabilise balance and reduce fall risk using low-frequency sound cues delivered through everyday listening devices. It is inspired by recent findings showing that 100 Hz auditory stimulation can reduce motion sickness by activating the otolithic organs of the inner ear. The approach discussed here is non-invasive, low-risk, and suitable for wide deployment. It could complement existing hearing aids, wearables, or public address systems in transport and care environments. This framework is not a commercial product, but an openly shared concept intended to encourage discussion and collaborative refinement.
