About this app

Sound Spice plays a gentle 100 Hz pure tone that may help reduce motion-sickness symptoms like nausea, dizziness and cold sweat. Recent human studies suggest that 1 minute of a 100 Hz tone, delivered safely through both ears, can stimulate the inner ear’s balance system and alleviate motion sickness before or during travel.

How it works

Researchers report that short exposure to a 100 Hz tone at everyday sound levels improved balance and autonomic responses linked to motion sickness in simulators and real rides. The effect has been nicknamed “sound spice.”
