Sound, Ears, Brains and the World

Josh McDermott, Professor of Brain and Cognitive Sciences at MIT, describes the early stages of human auditory processing and addresses how important information about the world can be derived from sound. Combining studies of auditory perception and computational modeling, Dr. McDermott shows how the brain may take advantage of regularities in how reverberation manifests itself in the complex signal that enters the ear, in order to distinguish multiple sound sources, often referred to as the Cocktail Party problem - Resources: Josh McDermott’s website - McDermott, J.
