In program three, ear anatomy and physiology are discussed and illustrated with clear graphics. This is followed by a discussion of the two primary types of hearing loss, conductive and sensorineural. The most common types of conductive loss – wax buildup, foreign object, abnormal bone growth, swelling, and tumor – are described, as are the two most common types of sensorineural loss – aging and repetitive exposure to loud noise. Other causes of hearing loss discussed include ototoxic medications, infection, head injury, otosclerosis, acoustic neuroma, and Ménière’s disease. Signs and symptoms of hearing impairment and methods for facilitating communication with individuals with hearing loss are included.
