More precise hearing implants created in Russia

In Russia, a group of scientists developed a hearing implant that reduces noise distortion by 17 %, increasing the precision of perception, as it transmits 9 % through the skull bones directly to the inner ear.

Scientists from Perm National Research Polytechnic University collaborated with colleagues from Perm State Medical University and the Russian Medical University to develop a new, more efficient hearing implant.

The implant is a bone conduction hearing aid. By transmitting sound through bone conduction, unlike conventional hearing aids, these devices bypass damaged parts of the auditory system in people with congenital ear abnormalities, trauma, or middle ear diseases.

In this innovation, the Russian engineers elegantly solved the problem of signal distortion and loss that occurs because standard metal fittings do not always guarantee a tight contact between the device’s components, resulting in some vibrations being lost.

The new design features a flat platform for the adapter between the vibrating element and the titanium implant, allowing for a tighter fit and more efficient vibration transmission. A polymer ring was also added to dampen unnecessary vibrations and reduce interference. Tests showed that this design transmits sound better across all frequencies.

Another development by the scientists is a special program for designing a customized hearing implant. According to the engineers, “the doctor inputs the parameters of the skull and bone tissue, and the system automatically builds a 3D model of the adapter, ideal for the individual.”
