The study used a hearing system that responds to a person's own brain waves.
Nima Maskarani of Columbia University says the system detects a special signal produced when the brain is trying to focus on a specific sound.
That gives us a signature that we can look at someone's brain and then we can decide, oh yeah, this is the source that they want to listen to.
When the signal appeared, the system automatically amplified the corresponding voice and filtered out competing voices.
Researchers say a hearing aid that works this way could solve a major problem for people with hearing loss, picking out one voice in a crowded room filled with speakers.
