Samsung's Hearapy App Uses 100 Hz Sound to Fight Motion Sickness
Samsung launched Hearapy, a mobile app that streams a precise 100 Hz sine wave to the inner ear to stimulate the vestibular system, claiming about 60 seconds of listening can relieve motion sickness for up to two hours. The approach is based on Nagoya University research and may work with Galaxy Buds 4 Pro, though tests suggest it can function with other headphones as well; the app is available on Google Play.
