The Science Behind It

Recent research published in Environmental Health and Preventive Medicine (2025) has demonstrated that just 1 minute of exposure to a 100 Hz pure tone can significantly reduce motion sickness symptoms.

Key Research Findings:
  • The 100 Hz tone activates vestibular function in the inner ear, improving balance
  • Effects last up to 120 minutes after a brief exposure
  • Reduces both objective symptoms (measured by posturography) and subjective symptoms
  • Works for various motion environments (vehicles, boats, simulators)
  • Most effective when played to both ears before the motion experience
