This week John and Stewart continue their chat with Susan. In Part 1, “A Tour of Duty”, Susan described her life in the studio working with artists including Prince, The Jacksons and Barenaked Ladies. In this episode, Susan describes how and why she left the studio for the laboratory to pursue a doctorate in audio psychoacoustics. Listen and learn as Susan describes how we hear, how and why our hearing changes as we age and why we perceive music the way we do. You’ll likely come away with a new perspective on this thing that we call ‘music’ and have a glimpse into current research aimed at discovering what we don’t as yet understand.
