Why study music: part IVa
About ten years ago, I was startled by a headline that, in essence, said if you wanted a spouse or friend who picked up your most subtle emotional cues, find a musician. Intrigued, I tracked down the research behind the article and discovered the work of Dr. Nina Kraus, Director of the Auditory Neuroscience Lab (Brainvolts) at Northwestern University.
The Lab was already known at that time for its work on the neurobiology of music and speech perception (see previous post). This particular study found that, not only were musicians better able to process the emotion in sound than non-musicians, but the ability was directly related to the number of years of experience of the musician and the age at which he/she began to study.

Our lives in sound
Our lives are filled with sound. On average, Americans listen to music for more than 32 hours a week (Nielsen 2017 study). We spend hours in conversation with co-workers, friends and families. We hear the everyday sounds of traffic, appliances in our homes, television, athletic events, pets, and a great deal more. We never think about what our brains do with all of that – sometimes competing – auditory information.
But according to Dr. Nina Kraus, Director of the Auditory Neuroscience Lab (Brainvolts) at Northwestern University, making sense of sound is one of the most computationally complex tasks we ask our brains to do. Not only is there a staggering amount of information to process (something on the order of 9 million bits of data per second1), we have to process information in microseconds in order to respond if necessary.
