In the United States, over 30 million people have hearing impairment, which comes to about 1 in every 8 people. 30 to 40 percent of people who are over 65 have major hearing loss.

Hearing Damage

Good hearing depends on a series of events that change sound waves into electrical signals that travel through our cells and nerves to our brains. When the hair cells (cilia) or auditory nerves that make this happen are damaged, your hearing is affected. Most people think of hearing loss (deafness) when the ear is damaged, but you can have other symptoms, too. You may hear a ringing or roaring sound. Most cases of hearing damage in those over 65 are caused by aging and heredity, but doctors are increasingly concerned about hearing damage in young patients, such as those who are exposed to loud on-the-job noises or recreational noise). It's important to understand the causes of hearing loss and what you can do to prevent it.
