In a recent study published in the journal Nature Neuroscience, researchers developed a brain-controlled hearing system that can help people focus on a single voice in noisy environments. They recorded real-time brain activity from patients undergoing neurosurgery and tested the system’s ability to identify the attended speaker and amplify that speaker's voice.
