What causes hearing loss?

This BBC Learning English 6 Minute English podcast episode focuses on age-related hearing loss. Neil and Georgie, the hosts, discuss the process of hearing, including the roles of the outer, middle, and inner ear, and the three smallest bones in the human body located within the ear. They interview an ear, nose, and throat surgeon and a BBC Radio 4 presenter to explain the science behind hearing loss, including the concept of "wear and tear" and the body's redundancy systems. The episode concludes with a quiz question and a review of key vocabulary terms.
