Answer to Question 1

Changes associated with aging can begin with the skin of the auricle becoming dry and wrinkled. Production of cerumen declines and it is drier. There is also dryness of the external auditory canal, which causes itching. Hairs in the external canal become coarser and longer, especially in males. The eardrum thickens, and the bony joints in the middle ear degenerate. Changes in the inner ear affect sensitivity to sound, understanding of speech, and balance. Degenerative changes include atrophy of the cochlea, the cochlear nerve cells, and the organ of Corti. These changes lead to the hearing loss which is common in the older adult. Noisy surroundings make it difficult for older adults to discriminate between sounds, thereby impairing communication and socialization. The hearing distance of older adults may also be impaired.
