Hearing Loss

People over age 50 are likely to lose some hearing each year. The decline is usually gradual. About 30% of adults age 65 through 74 and about 50% of those age 85 and older have hearing problems.


Hearing problems can get worse if they are ignored and not treated. People with hearing problems may withdraw from others because they may not be able to understand what others say. Hearing loss can cause an older person to be labeled “confused” or “senile.”

Signs &




to Ask

Self-Care /

•  Words are hard to understand. This worsens when there is background noise.

•  Certain sounds are overly loud or annoying.

•  Hearing a hissing or ringing background noise. This can be constant or it can come and go.

•  Concerts, TV shows, etc. are less enjoyable because much goes unheard.

Presbycusis (prez-bee-KU-sis). This is a gradual type of hearing loss. It is common with aging. With this, you can have a hard time understanding speech. You may not tolerate loud sounds. You may not hear high pitched sounds. Hearing loss from presbycusis does not cause deafness.

•  Ear wax that blocks the ear canal.

•  A chronic middle ear infection or an infection of the inner ear.

•  Medicines (e.g., aspirin).

•  Blood vessel disorders, such as high blood pressure.

•  Acoustic trauma, such as from a blow to the ear or from excessive noise. Noise-Induced Hearing Loss (NIHL) can be from a one-time exposure to an extremely loud sound or to repeated exposure to loud level sounds.

•  Ménière’s disease. This is a problem of the inner ear. The hearing loss comes and goes. Dizziness is also a symptom.

•  Small tumors on the auditory nerve. Brain tumor (rarely).

•  Hearing aid(s). These make sounds louder.

•  Speech reading. This is learning to read lips and facial expressions.
