An experimental brain-controlled hearing aid identifies and amplifies only what the wearer wants to hear.
The prototype hearing aid was designed by a team from Columbia University to mimic the brain’s ability to tune into selected sounds. Based on the team’s previous discovery that the brain waves of the listener take on the same form as the speaker, the AI-powered hearing aid monitors the brain waves of the wearer to detect who they are listening to. Once the individual speaking voice has been determined, the device will amplify it above the other sounds. The system does not need to be preprogrammed for specific voices, and will automatically adjust as new people enter the environment.
