How our brain makes sense of a noisy world, with Nina Kraus, PhD

Our life experiences shape the way that our brain processes sound, and sound is deeply intertwined with everything from our ability to read to our cognitive health as we age. Dr. Nina Kraus, of Northwestern University, talks about why we undervalue our sense of hearing; why musicians, athletes and bilingual people often have superior sound-processing abilities; why sound is crucial to language and reading; and how unwanted noise can harm not only our ears but also our brain.
