through the noise
Imagine a crowded room. It's a chaos of sound, teeming with indistinct
voices.
Scientists call this the cocktail party problem. To overcome it, most
people are able to focus on a single speaker's voice, which cues the
brain to amplify that sound and turn down the rest.
...
Now, in the journal Nature Neuroscience, a team describes a solution
that decodes a person's brain waves to choose which voice their
hearing system will amplify.
...
But so far, the approach has been tested only on four people with
typical hearing, says Josh McDermott, who runs the Laboratory for
Computational Audition at MIT and was not involved in the study.
Whether the system will work as well for people with hearing loss
remains an "open question," he says.
...
The new research is based on a discovery made in 2012 by Mesgarani and
Dr. Eddie Chang, a neurosurgeon at the University of California, San
Francisco.
The finding helps explain how the brains of people with typical
hearing are able to solve the cocktail party problem by selecting one
voice to amplify while filtering out others.
...
"When you look at the brain of a listener at the cocktail party,"
Mesgarani says, "what you see is that these brain waves are tracking
only the sound that [the listener] is focusing on, and not the other
sources."
