Washington D.C., [USA], April 11 (ANI): Researchers have found that employing a gadget which emits a particular frequency of sound to stimulate the inner ear can alleviate motion sickness symptoms.
A mere sixty seconds of exposure to a distinct audio stimulus, referred to as 'sound spice,' was enough to decrease dizziness and unease experienced by individuals tasked with reading documents inside a moving vehicle. These results indicate an uncomplicated and efficient method for mitigating this widespread issue.
A team headed by Takumi Kagawa and Masashi Kato from the Nagoya University Graduate School of Medicine conducted the research.
"Our research showed that brief exposure to a distinctive sound known as 'Sound Spice®' helps reduce symptoms of motion sickness, including nausea and dizziness," stated Kagawa.
"The sound level remains within the typical range for daily environmental noise exposure, indicating that the technology is both efficient and safe," noted Kagawa.
This finding significantly broadens our understanding of recent research regarding sound and its impact on the inner ear.
Growing evidence indicates that activating the portion of the inner ear responsible for balance through exposure to a specific sound might enhance balance function. In their study involving both mice and human subjects, the scientists determined that a frequency of 100 Hz was most effective.
Kato pointed out, "The distinct vibrations activate the otolithic organs in the inner ear, responsible for sensing linear acceleration and gravity."
"This suggests that a unique sound stimulation can broadly activate the vestibular system, which is responsible for maintaining balance and spatial orientation" added Kato.
To evaluate the efficacy of these devices, they enlisted willing subjects who listened to distinctive sounds. Afterward, motion sickness was triggered using either a swinging movement, a driving simulation, or actual vehicular travel.
The researchers utilized postural stability, ECG measurements, and Motion Sickness The Assessment Questionnaire outcomes are used to evaluate the efficacy of the stimulation.
The study revealed that symptoms like "dizziness" and "queasiness," commonly associated with motion sickness, were reduced.
According to Kato, these findings indicate that the activation of sympathetic nerves, typically impaired in motion sickness, was notably enhanced through the specific sound therapy administered.
Kagawa stated that the health risk associated with brief exposure to our distinctive sound is negligible.
As the stimulus intensity is significantly lower than the thresholds set for workplace noise safety, this form of stimulation should be considered safe provided it is used correctly.
Their findings point to a secure and efficient method to alleviate motion sickness, which could assist millions of affected individuals. The team intends to advance this technology with the objective of implementing it across various forms of transportation such as flights and voyages at sea. (ANI)
