Hearing loss is generally incurable but often treatable. Learn about hearing loss symptoms, causes, treatment and prevention.
Hearing loss is the partial or complete loss of hearing in one or both ears, ranging from mild to profound. There are many causes, and it can affect anyone at any age, but it's most common in people older than 60. Hearing loss in older adults is known medically as presbycusis.
How common is it? Statistics show that about 16% of U.S. adults have hearing loss, making it twice as common as diabetes or cancer. About 20% of men and 13% of women report they have at least some trouble hearing.
Hearing loss is usually incurable but treatable. By learning more about the symptoms, types, causes, tests, treatments and prevention of hearing loss, it is easier to understand how it impacts you or your loved one—and what you can do about it.
Symptoms of hearing loss
The symptoms of hearing loss can vary depending on the type of hearing loss, the cause of hearing loss, and the degree of loss.
For people with age-related hearing loss, it's typical to experience what's known as high-frequency hearing loss. Higher-pitched sounds, such as women's voices and birds chirping, may be harder to hear.
In general, people who have hearing loss may experience any or all of the following:
Types of hearing loss
There are three main types of hearing loss:
Causes of hearing loss
There are many causes of hearing loss, and it's important to figure out what is causing the hearing loss to determine the right treatment.
Hearing loss risk factors
Any of the following scenarios increase your risk of developing gradual hearing loss:
The more of these risk factors you have, the more likely you will experience hearing loss. Hearing loss is usually gradual.
Less common causes of hearing loss
Hearing loss also can be caused by any of the following conditions:
Tests for hearing loss
If you suspect you have a hearing loss, it is important to immediately seek the advice of a qualified hearing healthcare professional, such as an audiologist or hearing instrument specialist. Hearing tests are simple, painless, and widely available. Your hearing health professional will begin by conducting a thorough history, and they will ask questions about the challenges you are having, your lifestyle and your communication needs.
There are different types of hearing tests that evaluate specific parts of the auditory system and specialized hearing tests just for newborns, infants and toddlers. However, most hearing tests involve a sound-treated room or booth and headphones. Your hearing care professional will also conduct a visual exam of your ear canals and eardrum using a lighted instrument called an otoscope. This will determine if something physical, such as earwax, is contributing to your hearing loss.
Once in the booth, you will be asked to listen to a variety of tones and indicate the softest tones you can hear by pressing a button. This part of the exam is called pure tone audiometry, and it is valuable for determining not only how much hearing loss you have, but which frequencies are most affected. You may also be asked to listen for and repeat words. These speech tests can determine the softest speech sounds you can hear and how well you can understand speech clearly when it is loud enough for you to hear it.
If the hearing healthcare professional determines it is necessary, you may also be asked to wear plastic or soft foam earplugs during tests for acoustic reflexes. Another test called tympanometry assesses the function of your eardrum.
Test results are marked and presented on a graph called an audiogram. An audiogram displays the softest sounds you can hear at different pitches. These results will enable your hearing healthcare provider to assess your hearing ability and develop the right treatment plan if necessary.
Online hearing checks also are available. While online hearing tests cannot replace the thorough test a hearing healthcare professional provides, they can be a good place to start.
Hearing loss treatments
Hearing loss is generally not curable, but it is almost always treatable.
There are three main treatments for hearing loss:
Assistive listening devices also help in specialized hearing situations (such as needing a bed-shaker alarm if you can't hear a standard fire alarm).
Finding the right treatment is a joint venture between you and your hearing care professional, and if done properly, takes into consideration the following factors:
In some cases, hearing loss, especially conductive hearing loss, can be medically or surgically corrected but others cannot.
The most common treatment for sensorineural hearing loss is properly fitted hearing aids. Hearing aids are widely available in a range of styles, colors, sizes, technology levels, and price points. The great news? They do more than just help you hear—hearing aids will make you healthier overall, too. Increasingly, cochlear implants are a good treatment option for people who aren't helped enough by hearing aids.
Hearing loss prevention
Just because hearing loss is common doesn’t mean everyone is destined to be affected by it. There are many ways to prevent hearing loss or stop it from getting worse.
Most importantly, protect yourself against noise-induced hearing loss. Some noisy occupations can increase your risk of developing hearing loss. This cause of hearing loss is the easiest type to prevent by limiting exposure to loud noise and wearing hearing protection.
Hearing protection generally comes in the form of earplugs, earmuffs or noise-canceling headphones. Earplugs are made of acoustically impenetrable materials. When sized correctly and inserted into the ear, they can provide a good deal of hearing protection. Earmuffs or noise-cancellation earphones are others options for hearing protection. These devices offer greater protection against prolonged or higher levels of noise. These devices work by covering the entire ear to block or cancel out loud noises.
The hidden dangers of untreated hearing loss
Hearing loss can have far-reaching implications for you and those close to you. Untreated hearing loss can impact your health as well as your well-being. Research indicates that people with hearing loss have higher rates of depression, anxiety. It also causes under-stimulation of the brain, known as auditory deprivation.
The good news? Hearing aids delay dementia and provide other health benefits.
Medically, people with hearing loss face higher medical costs for other health issues and a higher risk of dangerous trips and falls.
For people still in the workforce, hearing loss is linked to unemployment and lower earnings at work.
Fortunately, hearing loss is well-understood and often treatable with hearing aids. By seeking information here, you’ve taken a smart first step.
Children and hearing loss
Hearing loss is harmful to people of all ages, but for children, it has special implications. Because babies and young children need to hear in order to develop spoken language, good hearing is the foundation for spoken communication, social development and educational success.
Hearing loss in children can be caused by congenital factors, head trauma, medications, childhood illnesses, persistent middle ear infections, deformities of the ear canal or malfunctioning eardrums. Treatment of childhood hearing loss depends largely on the underlying cause. Identification of hearing loss and intervention prior to 6 months of age has been shown to dramatically improve outcomes for kids.
Hearing loss stigma
We know that if you have hearing loss or if someone close to you is affected, the feeling can be overwhelming and maybe a little confusing. Hearing loss stigma is real, and keeps many people from seeking help. You may have a deep emotional reaction to finding out you or a loved one has hearing loss. The good news? Today's hearing aids are discreet and come with amazing technological advances, such as Bluetooth connectivity.
