Summary

Story summary

Columbia researchers demonstrated a brain-controlled hearing system that isolates a voice in noise.
The prototype used implanted electrodes in epilepsy patients listening to two overlapping talks.
Algorithms decoded real-time brain-wave patterns to identify the attended speaker, improving intelligibility and lowering effort.
The study, published in Nature Neuroscience on May 11, 2026, reported that volunteers preferred the assisted condition and noted 430 million people have disabling hearing loss, targeting wearable brain-sensing devices.
