Samsung's Hearapy app addresses motion sickness by using sound to alleviate symptoms. It is based on a study from Nagoya University that found exposure to a 100Hz tone for one minute can reduce motion sickness. The app emits a 100 Hz bass sine wave at 80-85dB through earphones, engaging the vestibular system to override conflicting sensory signals. Listening for 60 seconds can provide about two hours of relief. The app is available on the Google Play Store and works with any Android device. For optimal results, users should listen at a high volume, and Samsung recommends using Galaxy Buds 4 Pro for best sound quality. Other compatible options include the Soundpeats H3 and Bose QuietComfort Ultra 2. The Puro Sound Labs PuroPro is suggested for younger users due to its volume limit.
