About 25 percent of people in the United States between the ages of 55 and 64 have some degree of hearing impairment. For those older than 65, the number of people with some hearing loss is almost 1 in 2.
Aging and chronic exposure to loud noises are significant factors that contribute to hearing impairment.
Other factors, such as excessive earwax, can temporarily prevent your ears from conducting sounds as well as they should.
