New bionic device helps brain understand sounds in profound deafness

Chinese researchers have developed a bionic device that enables the brain to 'understand' sounds rather than merely 'hear' them, marking a shift from perception recovery to functional reconstruction. The device, described as a neuromorphic interface, was published in Nature Materials. Source: Milenio, Infobae

The technology

The device filters, analyzes, and codes sound information similar to a natural auditory nerve before transmitting meaningful signals to the brain. Unlike conventional cochlear implants, which rely on a fixed clock and limited electrodes, this interface integrates sound capture, neural coding, semantic processing, and bioelectric output.

Key differences

• Cochlear implants require a functional auditory nerve; if the nerve is damaged or absent, they become ineffective. The new device can bypass this by substituting the nerve's function. Source: Milenio
• Current implants struggle in noisy environments; the new system aims to improve speech recognition in complex acoustic settings. Source: Infobae

Current status

The device is still in the research stage and must undergo further testing before becoming available to patients. Both sources emphasize it as a decisive step toward a new generation of hearing restoration technology.
