Vehicle Motion Sound Control for Motion Sickness Mitigation

The patent replaces the mechanical wearable device system with an acoustic field-based system. Instead of requiring physical glasses or panels that occupants must wear, the invention uses sound waves (specifically low-frequency sounds around 19Hz) to create a virtual visual effect that reduces motion sickness. This substitutes mechanical intervention with acoustic field intervention, eliminating the need for wearable equipment while maintaining the motion sickness reduction effect.

The patent extracts the essential function of motion sickness reduction from the complex wearable device system and isolates it to a simple acoustic stimulus. By taking out only the necessary element (low-frequency sound around 19Hz) that produces the visual-vestibular synchronization effect, the invention eliminates the need for complex wearable hardware while preserving the therapeutic effect.

The patent creates a universal motion sickness reduction solution that works across multiple conditions and scenarios. The acoustic field-based approach using low-frequency sounds (19Hz) produces a virtual visual effect that synchronizes with vehicle movements regardless of the occupant's gaze direction or body position. This single acoustic stimulus mechanism serves multiple functions: it works when the occupant is stationary, when moving, when gazing at different objects, and during various vehicle maneuvers, making the system highly adaptable without requiring different devices for different conditions.
