What is hearing loss?

Hearing loss is a sudden or gradual decrease in how well you can hear. Gradual hearing loss happens over time. It can affect people of all ages. Hearing loss may range from slight to profound. Depending on the cause, hearing loss may improve with treatment (reversible) or be lasting (permanent).

What causes it?

The most common causes of hearing loss are noise and aging. Being exposed to everyday noises, such as using a power lawn mower, can lead to hearing loss over many years. As you get older, changes in the inner ear, Opens dialog cause slow but steady hearing loss. Many other things can cause hearing loss too.

What are the symptoms?

Common symptoms of hearing loss include muffled hearing and a feeling that your ear is plugged. You may have trouble understanding what people are saying, especially when there is background noise, such as a radio. You may listen to the TV or radio at a higher volume than in the past.

How is it diagnosed?

Your doctor will do a physical exam and ask about your symptoms and past health. The doctor also may look in your ears with a lighted device. If your doctor thinks that you have hearing loss, you'll have hearing tests to check whether you have hearing loss and how severe it is.

How is hearing loss treated?

Treatment depends on the type and cause of hearing loss. Permanent hearing loss can be treated with hearing aids, Opens dialog or devices that alert you to sounds around the house like the doorbell. If hearing aids don't work for you, cochlear implants may be an option. Reversible hearing loss can often be treated successfully.

Cause

The most common causes of hearing loss are:

Noise.

Noise-induced hearing loss can happen slowly over time. Being exposed to everyday noises, such as listening to very loud music or using a power lawn mower, can damage the structures of the inner ear, Opens dialog. This can lead to permanent hearing loss. Sudden, loud noises, such as an explosion, can also damage your hearing.

Aging.

In age-related hearing loss, changes in the inner ear that happen as you get older cause a slow but steady hearing loss. The loss may be mild or severe. It is always permanent.

Other causes of hearing loss include earwax buildup, an object in the ear, injury to the ear or head, an ear infection, a ruptured eardrum, and other conditions that affect the middle or inner ear. Some medicines also can cause it. And some people are born with hearing problems.

Prevention

Being exposed to loud noise over and over is one of the most common causes of permanent hearing loss. It usually develops slowly and without pain or other symptoms. You may not notice that you have hearing loss until it is severe.

Here are some steps you can take to lower your risk of noise-induced hearing loss.

• Be aware of and avoid harmful noise.

  You can be exposed to harmful noise at work, at home, and in many other settings. Know what kinds of situations can cause harmful noise levels. To learn more about hearing protection in workplaces in the United States, contact the Occupational Safety and Health Administration (OSHA).

• Use hearing protectors.

  If you know you are going to be around harmful noise, wear hearing protectors, such as earplugs or earmuffs.

• Control the volume when you can.

  Reduce the noise in your life by turning down the volume on the stereo, TV, or car radio, and especially on personal listening devices with earphones or ear buds.

• Don't wait to protect yourself.

  After noise-related damage to the ear is done, it cannot be reversed. But if you already have some noise-related hearing loss, it is not too late to prevent further damage and preserve the hearing that you still have.

Preventing hearing loss not caused by noise

Being exposed to loud noise over and over is one of the most common causes of permanent hearing loss. But there are other causes of hearing loss. Here are some steps you can take to lower your risk of other types of hearing loss.

• Don't put anything in your ear.

  Never stick a cotton swab, hairpin, or other object in your ear to try to remove earwax or to scratch your ear. The best way to prevent earwax problems is to leave earwax alone.

• Swallow and yawn during a plane landing.

  If you have an upper respiratory problem (such as a cold, the flu, or a sinus infection), take a decongestant a few hours before landing or use a decongestant spray just before landing.

• Stop smoking.

  You are more likely to have hearing loss if you smoke.

• Get immunizations.

  Receive all the recommended immunizations to protect against pneumococcal disease, meningitis, and other conditions that can cause hearing problems.

Symptoms

Common symptoms of hearing loss include:

• Muffled hearing and a feeling that your ear is plugged.
• Trouble understanding what people are saying. This is most common when other people are talking or when there is background noise.
• Listening to the TV or radio at a higher volume than in the past.

Other symptoms may include:

• A ringing, roaring, hissing, or buzzing in the ear (tinnitus).
• Ear pain, itching, or irritation.
• Pus or fluid leaking from the ear.
• A feeling that you or your surroundings are spinning (vertigo).

People who have hearing loss are sometimes not aware of it. Often, family members or friends are the first to notice the hearing loss.

Social situations can be tiring and stressful for people who don't hear well. They may start to avoid those situations as their hearing loss gets worse. Many adults become depressed because of how hearing loss affects their relationships and social life.

What Happens

Hearing loss can happen slowly or suddenly. It's often a natural result of aging. Long exposure to loud noise can make it worse. If hearing loss is caused by something that can be treated, hearing will sometimes come back. But most hearing loss is permanent. Hearing aids and other devices can help.

Types of hearing loss

Hearing loss can be temporary or permanent.

• In conductive hearing loss, sound is blocked before it reaches the inner ear. This type of hearing loss may be temporary or reversible. For example, a buildup of wax in the ear or an ear infection can cause hearing loss that goes away with treatment.
• In sensorineural hearing loss, sound reaches the inner ear. But a problem in the inner ear or in the nerves that allow you to hear prevents proper hearing. This type of hearing loss is usually permanent. Hearing loss caused by exposure to loud noise over time is an example of this type of hearing loss. Another example is age-related hearing loss.
• In mixed hearing loss, you have both sensorineural and conductive hearing loss.

Hearing loss can range from slight to moderate to profound.

When to Call a Doctor

Self-Care

• Avoid loud noises whenever possible. This helps keep your hearing from getting worse.
• Always wear hearing protection around loud noises.
• Wear a hearing aid as directed.
  • A professional can help you pick a hearing aid that will work best for you.
  • You can also get hearing aids over the counter for mild to moderate hearing loss.
• Have hearing tests as your doctor suggests. They can show whether your hearing has changed. Your hearing aid may need to be adjusted.
• Use other devices as needed. These may include:
  • Telephone amplifiers and hearing aids that can connect to a television, stereo, radio, or microphone.
  • Devices that use lights or vibrations. These alert you to the doorbell, a ringing telephone, or a baby monitor.
  • Television closed-captioning. This shows the words at the bottom of the screen. Most new TVs can do this.
  • TTY (text telephone). This lets you type messages back and forth on the telephone instead of talking or listening. These devices are also called TDD. When messages are typed on the keyboard, they are sent over the phone line to a receiving TTY. The message is shown on a monitor.
• Use text messaging, social media, and email if it is hard for you to communicate by telephone.

Hearing Devices

If you have hearing loss, you may find that it takes extra effort and energy to talk with others. Hearing may be especially difficult in settings where there are many people talking or there is a lot of background noise. The increased effort it takes to be with other people may cause stress and fatigue. You may begin to avoid social activities, feel less independent, and worry about your safety.

Hearing devices you may want to use include:

Hearing aids.

Hearing aids make all sounds louder (amplify), including your own voice. Common background noises, such as rustling newspapers, magazines, and office papers, may be distracting. When you first get hearing aids, it may take you several weeks to months to get used to this. Most hearing aids can be adjusted to fit your hearing loss and reduce background noise.

Assistive listening devices.

These devices make certain sounds easier to hear by bringing the sound directly to your ear. They shorten the distance between you and the source of sound and also reduce background noise. You can use different types of devices for different situations, such as one-on-one conversations and classroom settings or auditoriums, theaters, or other large public spaces. Commonly used listening devices include telephone amplifiers, personal listening systems (such as auditory trainers and personal FM systems), and hearing aids that you can connect directly to a television, stereo, radio, or microphone.

Alerting devices.

These devices alert you to a particular sound (such as the doorbell, a ringing telephone, or a baby monitor) by using louder sounds, lights, or vibrations to get your attention.

Closed-captioning.

Closed-captioning shows the words at the bottom of the screen while you're watching TV or your computer screen. Most newer TVs and online programs have a closed-captions option.

Text messaging.

You can type messages and send them from your mobile device to someone else's. You can also use voice-to-text if you have trouble typing.

TTY (text telephone).

A TTY (also called TDD, or telecommunication device for the deaf) allows you to type messages back and forth on the telephone instead of talking or listening. When messages are typed on the TTY keyboard, the information is sent over the phone line to a receiving TTY and shown on a monitor. A telecommunications relay service (TRS) makes it possible to call from a phone to a TTY or vice versa.

Many other communication devices, such as pagers, fax machines, email, and custom calling features offered by phone companies, can be helpful. To get more information about selecting and using listening, alerting, and telecommunicating devices, talk to an audiologist.
