Use Case

Road Trip Travel Comfort

A drug-free 60-second sound session for long drives.

100 Hz sound — a calm 60-second listening session for travel

The Science

Long drives can bring on motion discomfort through extended exposure to acceleration, braking, and turns. Stop-and-go traffic, winding roads, and reading in the car are common triggers.

Stillwave plays a fixed 100 Hz pure tone through earbuds as a listening session before motion starts. The tone reaches the inner ear, where the otoconia — the balance structures involved in sensing linear movement — are located.

For drives over 2 hours, simply replay the 60-second tone at a rest stop. The app's countdown timer shows when it's time.

Frequently Asked Questions

How often should I replay on a long drive?

The app's session timer runs up to 2 hours. For a 6-hour road trip, replay at your rest stops — roughly every 2 hours.

Can everyone in the car use it?

Yes. Each person plays the 60-second tone through their own earbuds. Multiple passengers can use Stillwave simultaneously.

What about winding mountain roads?

Winding roads are a stronger motion sickness trigger. Stillwave helps, but also try sitting in the front seat and looking at the road ahead.
