Summary

What we hear is incredibly personal and we all hear things differently. Sometimes our ears can even play tricks on us. Sonic illusions put a spotlight on the unique function of our hearing and how our backgrounds and biology affect how we process sound. Psychologist Dr. Diana Deutsch and neuroscientist Dana Boebinger explain why our hearing is a unique sense and why sonic illusions can fool us.  Twenty Thousand Hertz is produced out of the studios of Defacto Sound, and hosted by Dallas Taylor.  Follow Dallas on Instagram, TikTok and LinkedIn.
