What noise is doing to our brains

Nina Kraus talks about her new book, Of Sound Mind, and reflects on the impact of our contemporary, technologically-infused sonic world.

'We have to keep asking ourselves, is the sound necessary?', says neurobiologist

From traffic, to construction, to constantly wearing ear-buds, the byproduct of our contemporary technology-rich world is noise. Lots of it. 

What's that doing to our brains, and our well being?

Neurologist Nina Kraus spoke to Spark host Nora Young about her new book, Of Sound Mind: How Our Brain Constructs a Meaningful Sonic World.

While not all sounds are pleasant, they're all part of our auditory life. And it's not a simple matter of sound waves traveling to the brain. According to Kraus, our 'hearing brain' shapes how we understand the sounds around us, and that changes as our life experiences change.

"We're going to process it differently because we have different hearing brains based on our inherent biology and, especially because of how we have made sense of sound throughout our lives."
