Listen to ‘Sound Spice’ for Drug-Free Motion Sickness Relief

Researchers at Nagoya University have found that a specific audio tone may alleviate motion sickness. The sound, trademarked as "Sound Spice," is a 100 Hz tone at 65.9 dBa loudness, which stimulates the utricle in the inner ear to help maintain balance. Tests on mice and humans showed reduced symptoms of motion sickness when exposed to the sound before experiencing motion.
