The sounds our bodies make can tell doctors all kinds of surprising things about our health. In this episode, we unpack the history of sound in medical diagnosis, from Hippocratic times, to the invention of the stethoscope, to the specialized tools and AI systems used today. Along the way, we’ll hear detailed recordings of these medical sounds, and learn what each of them means. Featuring Dr. David Steensma and Dr. Daniel Weiss.
