We discuss the basics of hearing with Dr. Jonny. How does hearing work? What causes an ear infection? Why does your hearing get worse temporarily after going to a loud concert? How do you pronounce cochlea and did we just get canceled? How come some people can hear higher pitches? What happens when you pop your ears? What's happening in the ear when you have ringing in your ears? Are over headphones or earbuds better for your ears? Can humans use echolocation?
