By age 65, one person in three has some hearing loss. By age 75, it's one person in two. People who don't hear properly sometimes give odd answers to questions and are wrongly thought to be confused or uncooperative. People with hearing problems can get so frustrated that they stop trying to communicate and become withdrawn.
Presbycusis (progressive loss of hearing)
Presbycusis, or sensorineural hearing loss, is a gradual decline in sound reception that occurs as you get older. This happens because the eardrum loses its elasticity and the bones of the ear become stiffer. Sounds, particularly higher tones, are muffled. Words are hard to understand if there is a lot of background noise. At the same time, loud noise may be painful so when people raise their voice in an effort to be heard, they may be told, "Don't shout. I'm not deaf!" People with presbycusis should ask others to speak slowly and clearly. Hearing aids can be very helpful.
Conduction deafness
Conduction deafness is when sound waves are blocked as they pass through the ear. People with conduction deafness hear sounds from outside as muffled, but their own voice may seem louder than normal. Because of this, they often speak softly. The most common cause of conductive deafness is ear wax. Removal of the wax, after first softening it, will make a lot of difference. Other causes of conductive deafness in older people include ear infections, a tear or hole in the eardrum, and damage to the small bones in the inner ear that conduct sound waves.
Central deafness
Central deafness can also affect older people, although it is far less common than either presbycusis or conduction deafness. Central deafness is due to a problem within the hearing centers in the brain. Sounds can be heard, but language cannot be understood. Central deafness may follow a long illness with high fever, long exposure to loud noise, head injuries, stroke, tumors, and certain drugs. The deafness is permanent, but speech therapy may help communication.
Otosclerosis
Otosclerosis is a disorder of the bone around the inner ear. Another term for this disorder is otospongiosis, which means spongy bone. This disorder often occurs in the bones between the middle and the inner ear. Many people are unaware they have otosclerosis. When it affects the inner ear, deafness and dizziness may result. One or both ears may be affected. It is almost always accompanied by ringing in the ear, which is called tinnitus. Unlike some causes of hearing loss, a hearing loss caused by otosclerosis can be treated. Treatment includes surgery to stabilize or replace the small bones of the inner ear. Surgery can usually return hearing to a normal or near normal status. If surgery is not possible, a hearing aid may be helpful.
See your health care provider. He or she will examine your ears and may send you to an audiologist (hearing specialist) for special hearing tests. You may have earwax that needs to be removed. A hearing aid may be recommended.
Hearing aids are instruments that amplify sound for people who cannot hear well. Different hearing problems may require different kinds of hearing aids.
Tell people and ask them to speak clearly. If you don't hear the first time, ask people to repeat what they said a little louder. Ask people to face you when they speak, and watch their lips and body signs. Learn where to sit in groups or in an audience so that you can hear best.
Don't try to hide your hearing problem. It is nothing to be ashamed of and most hearing problems can be treated.
