New “Hearapy” app pairs with Galaxy Buds4 Pro
Samsung has introduced a new Android application designed to temporarily reduce motion sickness using sound. The app, called Hearapy, works in conjunction with the company’s Galaxy Buds4 Pro, though it can also be tested with other earbuds or headphones.
The concept is based on research conducted at the University of Nagoya in Japan. In that study, scientists found that exposure to a 100Hz sine wave played at approximately 75 to 85 decibels for several minutes appeared to alleviate symptoms of motion sickness by stimulating the body’s balance system.
How the technology works
Motion sickness is often linked to conflicting sensory signals between the eyes and the inner ear. The Japanese researchers concluded that a low-frequency tone could activate the vestibular system inside the ear, helping to recalibrate balance perception.
Samsung’s Hearapy app replicates those experimental conditions by generating a precise 100Hz tone. According to the findings referenced by the company, listening to the sound for about one minute may temporarily reduce motion sickness symptoms for up to two hours.
Usage and compatibility
Although Samsung recommends pairing the app with the Galaxy Buds4 Pro, the tone itself is not hardware-locked. Users may attempt playback through other earbuds or over-ear headphones, though effectiveness could vary depending on audio quality and output accuracy.
The volume should be set high enough to remain clearly audible but not at a level that causes discomfort. Because the method is temporary, the tone can be replayed as needed during travel or other situations where motion sickness symptoms arise.
Scientific inspiration
The Nagoya research suggests that controlled acoustic stimulation may offer a non-pharmaceutical option for short-term symptom relief. While the app’s real-world effectiveness may depend on individual sensitivity and listening equipment, it represents an example of how consumer technology can translate laboratory findings into accessible tools.
