Mind-controlled hearing aid allows the wearer to focus on particular voices
Previous work by Mesgarani’s lab found that it is possible to identify which person someone is paying attention to, as their brain activity tracks the sound waves of that voice most closely. The device compares the audio of each speaker to the brain waves of the person wearing the hearing aid. According to Jesal Vishnuram, technology manager at the charity Action on Hearing Loss, said that one of the reasons people find conventional hearing aids unpleasant in noisy environments is that their brain is out of practice at filtering sounds and so does this less effectively.
