Hearing loss is a common problem caused by noise, aging, disease, and heredity. People with hearing loss may find it hard to have a conversation with friends and family. They may also have trouble understanding a doctor’s advice, responding to warnings, and hearing doorbells and alarms.
Approximately one in three people between the ages of 65 and 74 have hearing loss, and nearly half of those older than 75 has difficulty hearing. But some people may not want to admit they have trouble hearing. Older people who can’t hear well may become depressed or may withdraw from others to avoid feeling frustrated or embarrassed about not understanding what is being said. Sometimes older people are mistakenly thought to be confused, unresponsive, or uncooperative because they don’t hear well.
Hearing problems that are ignored or untreated can get worse. If you have a hearing problem, see your doctor. Hearing aids, special training, certain medicines, and surgery are some of the treatments that can help.
Signs of Hearing Loss
Some people have a hearing problem without realizing it. You should see your doctor if you:
- Have trouble hearing over the telephone
- Find it hard to follow conversations when two or more people are talking
- Often ask people to repeat what they are saying
- Need to turn up the TV volume so loud that others complain
- Have a problem hearing because of background noise
- Think that others seem to mumble
- Can’t understand when women and children speak to you
Types of Hearing Loss
Hearing loss comes in many forms. It can range from a mild loss, in which a person misses certain high-pitched sounds, such as the voices of women and children, to a total loss of hearing.
There are two general categories of hearing loss:
- Sensorineural hearing loss occurs when there is damage to the inner ear or the auditory nerve. This type of hearing loss is usually permanent.
- Conductive hearing loss occurs when sound waves cannot reach the inner ear. The cause may be earwax buildup, fluid, or a punctured eardrum. Medical treatment or surgery can usually restore conductive hearing loss.
Age-Related Hearing Loss (Presbycusis)
One type of hearing loss, called presbycusis, or age-related hearing loss, comes on gradually as a person ages. It seems to run in families and may occur because of changes in the inner ear and auditory nerve. Having presbycusis may make it hard for a person to tolerate loud sounds or to hear what others are saying.
Age-related hearing loss most often occurs in both ears, affecting them equally. Because the loss is gradual, someone with presbycusis may not realize that he or she has lost some of his or her ability to hear.
Ringing in the Ears (Tinnitus)
Tinnitus, also common in older people, is typically described as ringing in the ears, but it also can sound like roaring, clicking, hissing, or buzzing. It can come and go. It might be heard in one or both ears, and it may be loud or soft. Tinnitus can accompany any type of hearing loss and can be a sign of other health problems, such as high blood pressure or allergies, or a side effect of medications.
Tinnitus is a symptom, not a disease. Something as simple as a piece of earwax blocking the ear canal can cause tinnitus, but it can also be the result of a number of health conditions.
Causes of Hearing Loss
Loud noise is one of the most common causes of hearing loss. Noise from lawn mowers, snow blowers, or loud music can damage the inner ear, resulting in permanent hearing loss. Loud noise also contributes to tinnitus. You can prevent most noise-related hearing loss. Protect yourself by turning down the sound on your stereo, television, or headphones; moving away from loud noise; or using earplugs or other ear protection.
Earwax or fluid buildup can block sounds that are carried from the eardrum to the inner ear. If wax blockage is a problem, try using mild treatments, such as mineral oil, baby oil, glycerin, or commercial ear drops to soften earwax. A punctured eardrum can also cause hearing loss. The eardrum can be damaged by infection, pressure, or putting objects in the ear, including cotton-tipped swabs. See your doctor if you have pain or fluid draining from the ear.
Viruses and bacteria (including the ear infection otitis media), a heart condition, stroke, brain injury, or a tumor may affect your hearing.
Hearing loss can also result from taking certain medications. “Ototoxic” medications damage the inner ear, sometimes permanently. Some ototoxic drugs include medicines used to treat serious infections, cancer, and heart disease. Some antibiotics are ototoxic. Even aspirin at some dosages can cause problems. Check with your doctor if you notice a problem while taking a medication.
Heredity can cause hearing loss, as well. But not all inherited forms of hearing loss take place at birth. Some forms can show up later in life. For example, in otosclerosis, which is thought to be a hereditary disease, an abnormal growth of bone prevents structures within the ear from working properly.
Ways to Cope with Hearing Loss
If you notice signs of hearing loss, talk to your doctor. If you have trouble hearing, you should:
- Let people know you have a hearing problem.
- Ask people to face you and to speak more slowly and clearly. Also, ask them to speak louder without shouting.
- Pay attention to what is being said and to facial expressions or gestures.
- Let the person talking know if you do not understand what he or she said.
- Ask the person speaking to reword a sentence and try again.
The most important thing you can do if you think you have a hearing problem is to seek professional advice. Your family doctor may be able to diagnose and treat your hearing problem. Or, your doctor may refer you to other experts, like an otolaryngologist (ear, nose, and throat doctor), or an audiologist ( a health professional who can identify and measure hearing loss).
Devices to Help with Hearing Loss
Your doctor or specialist may suggest you get a hearing aid. Hearing aids are electronic, battery-run devices that make sounds louder. There are many types of hearing aids. Before buying a hearing aid, ask if your health insurance will cover the cost. Also, ask if you can have a trial period so you can make sure the device is right for you. An audiologist or hearing aid specialist will show you how to use your hearing aid.
Assistive listening devices, alerting devices, and cochlear implants can help some people with hearing loss. Alert systems can work with doorbells, smoke detectors, and alarm clocks to send you visual signals or vibrations. For example, a flashing light can let you know someone is at the door or the phone is ringing. Some people rely on the vibration setting on their cell phones to alert them to calls.
Cochlear implants are electronic devices for people with severe hearing loss. They don’t work for all types of hearing loss.
