Ears And Hearing (2nd Ed, 1969)

The film “Ears and Hearing” (1969) provides an in-depth explanation of the human ear’s anatomy and the mechanics of hearing. It describes how sound waves are collected by the outer ear, transmitted through the auditory canal to the eardrum, and then amplified by the small bones in the middle ear. The film further explores the conversion of mechanical energy into electrochemical signals in the inner ear, detailing the role of the cochlea and the auditory nerve in processing sound. It also addresses hearing impairments, distinguishing between sensory and conductive deafness, and outlines treatment options, including surgery and hearing aids.
