Ears And Hearing (1949)

The film explores the anatomy and function of the human ear, detailing how sound waves travel through the outer ear, vibrate the eardrum, and are transmitted via three tiny bones in the middle ear to the inner ear. It explains the roles of the hammer, anvil, and stirrup in hearing, as well as the process of converting sound vibrations into nerve impulses sent to the brain. The film also discusses common issues affecting hearing, such as earwax buildup and middle ear infections, and highlights the importance of hearing aids for those with hearing impairments.
