A study by researchers from Wake Forest University School of Medicine highlights a new approach to combating driver’s hearing loss. A team of scientists, led by Mohammad J. Moghimi, Ph.D., assistant teacher of biomedical engineering, has designed a new type of hearing aid that improves hearing not only, but also offers a safe and non -invasive alternative to implantable devices and corrective surgeries.
The study recently published in Communications engineeringA Journal of the Portfolio of Nature.
The driver’s hearing loss, which occurs most often in childhood, occurs when sounds do not reach the inner ear. Sound waves are blocked in the outer or medium ear due to ear infections, blockages or structural anomalies.
“Treatment of conductive hearing loss may include corrective surgeries and implantable hearing aids, which can be very invasive, especially for pediatric patients,” said Moghimi. “Flexible hearing aids offer a non -invasive alternative.”
To produce vibrations strong enough to reach the cochlea, the part of the inner ear responsible for hearing, the research team has designed a flexible hearing aid. The device uses micro-epidermal actuators to create vibrations on the skin behind the ear, which then go directly to the inner ear, bypassing the ear canal.
For the study, 10 participants aged 19 to 39 wore earplugs and ears to simulate driver loss. The researchers then tested actuators’ tables to improve vibration strength, improve sound quality and control the vibration management.
“We found that using a table of these actuators, rather than one, considerably improves the strength and quality of vibrations, which led to better hearing results,” said Moghimi.
Moghimi has also noted that improving hearing in children can reduce delays in language development and speech and stimulate education development.
“This technology has the potential to improve the quality of life of children with hearing impairments and to transform the way we approach pediatric auditory aid,” said Moghimi.
The research team will then focus on a broader study to further assess the efficiency and safety of the device in children and adults.
