Samsung has a new app, Hearapy, that does pretty much exactly what its name suggests. It uses audio therapy to reduce motion sickness via earbuds. The app plays a calibrated 100 Hz bass sine wave at 85 decibels that recalibrates the discrepancy between what your inner ear senses and what your eyes are seeing. The inner ear detects the motion of a vehicle while your eyes, especially when focused on your phone screen or the page of a book, see that you are not moving. These conflicting signals trigger motion sickness.
Hearapy’s technology is backed by research from Nagoya University in Japan. For it to work you must listen to the sound for at least 60 seconds, and it lasts for about two hours. While it works best on Samsung’s new Galaxy Buds 4 Pro, you can use the app with most earbuds that can reproduce 100 Hz. Hearapy is available on the Google Play Store in the U.S. and India and it is compatible with non-Samsung smartphones.
