Although scientists have been exploring the mysteries of aging, there is currently no data explaining why we grow older. There is, however, plenty of evidence showing that our hearing diminishes with age, impacting an estimated one in three U.S. adults between the ages of 65 and 75, and about half of people over 75.
Biologists believe some of the causes may be attributed to free radicals, the environment and genetics.
The aging process affects many organs and body functions, including those most germane to hearing - brain and ears.
As the brain ages, it processes information detected by the ear slower, diminishing our ability to listen, hear and understand a conversation, especially when surrounded by background noise.
The sensory cells in the inner ear also deteriorate over time, causing our hearing to become less responsive to sound waves.
While there are no proven techniques to prevent age-related hearing loss, there are some sensible steps that can be taken, including healthy diet, exercise for the body and brain, as well as the use of hearing technology.
