Episode 78: Hearing

An explanation of the process of human hearing, covering the structure and function of the outer, middle, and inner ears, with a focus on explaining how the hair cells of the cochlea transduce mechanical motion into electrical signals that are interpreted as sound. I also discuss the mechanisms of sound localisation, some of the causes of deafness, and briefly outline the workings of the cochlea implant. Recommended pre-listening is Episode 53: Sound and Music.
