Summary

Close your eyes and just listen. Even if you aren’t actively thinking about the noises happening around you, your brain is constantly processing sound. That’s because, unlike your eyes, your ears never close. In fact, Northwestern neurobiology professor Nina Kraus, says listening is one of the hardest tasks we ask our brains to do. On today’s episode, Kraus explains how the sounds we’re surrounded by everyday – like a noisy leaf blower or the soothing sound of music – really matter and can impact our physical and mental health. Plus, she shares tips for building a healthy “sonic world.”  To learn more about how CNN protects listener privacy, visit cnn.com/privacy Learn more about your ad choices.

As a child, Nina Krauss' world was shaped by sound. She grew up in a family that spoke

practiced.

And yes, I still have that piano, I play it every day, my son played that piano when he

was a little boy.

But when Nina got to college, she found a new love, science. So she set out to find a way

1:09.8

to combine her love of music, love of language, and love of the brain.

1:15.2

And I thought, oh, I wanted to do this, want more biology. So the idea, even then, I realized

1:21.4

that I can combine language and biology. And sound is at this intersection.

1:30.6

And she did it. Today Nina is one of the leading experts in the field of sound. And she leads

1:37.4

a lab at Northwestern University called BrainVoltz, where she studies how our brains make sense

1:43.5

of all the sounds that surround us every day.

If you look at the homepage of our website, which I hope people do, you will see that we

research music and rhythm and bilingualism, reading, hearing loss, aging, concussion.
