Hearing loss happens for different reasons. Many people lose their hearing slowly as they age. This condition is known as presbycusis (prez-buh-KYOO-sis). Doctors do not know why presbycusis affects some people more than others, but it seems to run in families. Another reason for hearing loss with aging may be years of exposure to loud noise. This condition is known as noise-induced hearing loss. Many construction workers, farmers, musicians, airport workers, landscapers, and people in the military have hearing loss even in their younger and middle years because of exposure to loud noises. 

Hearing loss can also be caused by viral or bacterial infections, heart conditions, stroke, head injuries, tumors, and certain medicines.

Hearing loss can be serious. The most important thing you can do if you think you have a hearing loss is to seek advice from a health care provider. There are several types of professionals who can help you. You might want to start with your primary care physician, an otolaryngologist, an audiologist, or a hearing aid specialist. Each has a different type of training and expertise. Each can be an important part of your hearing health care. If you are told there is nothing that can be done about your hearing loss, seek a second opinion.

• An otolaryngologist (oh-toe-lair-in-GAH-luh-jist) is a doctor who specializes in diagnosing and treating diseases of the ear, nose, throat, and neck. An otolaryngologist, sometimes called an ENT, will try to find out why you’re having trouble hearing and offer treatment options. He or she might also refer you to another hearing professional, such as an audiologist.
• An audiologist (aw-dee-AH-luh-jist) has specialized training in identifying and measuring the type and degree of hearing loss. Some audiologists are licensed to fit hearing aids.
• A hearing aid specialist is someone who is licensed by your state to conduct and evaluate basic hearing tests, offer counseling, and fit and test hearing aids.

Your treatment will depend on the degree of your hearing loss, so some treatments will work better for you than others. There are a number of devices and aids that help you hear better when you have hearing loss. Here are the most common ones:

• Hearing aids are electronic instruments worn in or behind your ear. They make sounds louder. To find the hearing aid that works best for you, you might have to try more than one. Be sure to ask for a trial period with your hearing aid and understand the terms and conditions of the trial period. Work with your hearing aid provider until you are comfortable putting on and removing the hearing aid, adjusting the volume level, and changing the batteries. Hearing aids are generally not covered by health insurance companies, although some do. Medicare does not cover hearing aids for adults; however, diagnostic evaluations are covered if they are ordered by a physician for the purpose of assisting the physician in developing a treatment plan.
• Cochlear implants. Cochlear (COKE-lee-ur) implants are small electronic devices surgically implanted in the inner ear that help provide a sense of sound to people with more severe-to-profound hearing loss. Cochlear implants can be recommended for one or both ears. 
• Bone anchored hearing systems bypass the ear canal and middle ear and are designed to use your body’s natural ability to transfer sound through bone conduction. The sound processor picks up sound, converts it into vibrations, and then relays the vibrations through your skull bone to your inner ear.
• Assistive listening devices include phone amplifying devices, captioned phones, smart phone or tablet apps. Other systems for larger areas can be hearing loops, FM, or infrared systems in places of worship, theaters, and auditoriums.
• Lipreading or speechreading is often used to augment a hearing aid or cochlear implant to help people with hearing loss follow conversations. People who use this method pay close attention to others when they talk by watching the speaker’s mouth and body movements. Special trainers can help you learn how to lipread or speechread.

You and your family can work together to make living with hearing loss easier. Here are some things you can do:

• Tell your friends and family about your hearing loss. The more friends and family you tell, the more people there will be to help you cope with your hearing loss.
• Ask others to face you when they talk so that you can see their faces. If you watch their faces move and see their expressions, it might help you to understand them better.
• Ask people to speak louder, but not shout. Tell them they do not have to talk slowly, just more clearly.
• Turn off the TV or the radio when you aren’t actively listening to it.
• Be aware of noise around you that can make hearing more difficult. When you go to a restaurant, for example, don’t sit near the kitchen or near a band playing music. Background noise makes it hard to hear people talk.

Working together to hear better may be tough on everyone for a while. It will take time for you to get used to watching people as they talk and for people to get used to speaking lslowly and clearly. Be patient and continue to work together. Hearing better is worth the effort.

• Hearing loss is the third most common physical condition after arthritis and heart disease.
• Gradual hearing loss can affect people of all ages — varying from mild to profound. Depending on the cause, it can be mild or severe, temporary or permanent.
• Degrees of hearing loss: mild, moderate, severe, profound.
• Congenital hearing loss means you are born without hearing.
• Hearing loss is an invisible condition. Since hearing loss is often not visible, people might jump to the wrong conclusion that someone is aloof, confused, not smart, or has had a personality change.
• Noise and aging are the most common causes of hearing loss in adults. There is a strong relationship between age and reported hearing loss.
• Presbycusis, or age-related hearing loss, causes changes in the inner ear as you get older resulting in a slow but steady hearing loss. In older people, a hearing loss is often confused with, or complicates, conditions such as dementia.
• Noise-induced hearing loss may happen suddenly or gradually. Being exposed to everyday noises such as listening to loud music, being in a noisy work environment, or using a lawn mower can lead to hearing loss over many years.
• Sudden, noise-induced hearing loss from gunfire and explosions is the number one disability caused by combat in current wars. 
• More often than not, severe tinnitus (ringing in the ears) will accompany hearing loss and may be just as debilitating as hearing loss itself

• About 2 to 3 out of every 1,000 children in the United States are born with a detectable level of hearing loss in one or both ears.¹
• More than 90 percent of deaf children are born to hearing parents.²
• Approximately 15 percent of American adults (37.5 million) aged 18 and over report some trouble hearing.³
• Among adults aged 20-69, the overall annual prevalence of hearing loss dropped slightly from 16 percent (28.0 million) in the 1999-2004 period to 14 percent (27.7 million) in the 2011–2012 period.⁴
• Age is the strongest predictor of hearing loss among adults aged 20-69, with the greatest amount of hearing loss in the 60 to 69 age group.⁴
• Men are almost twice as likely as women to have hearing loss among adults aged 20-69.⁴
• Non-Hispanic white adults are more likely than adults in other racial/ethnic groups to have hearing loss; non-Hispanic black adults have the lowest prevalence of hearing loss among adults aged 20-69.⁴
• About 18 percent of adults aged 20-69 have speech-frequency hearing loss in both ears from among those who report 5 or more years of exposure to very loud noise at work, as compared to 5.5 percent of adults with speech-frequency hearing loss in both ears who report no occupational noise exposure.⁴
• One in eight people in the United States (13 percent, or 30 million) aged 12 years or older has hearing loss in both ears, based on standard hearing examinations.⁵
• About 2 percent of adults aged 45 to 54 have disabling hearing loss. The rate increases to 8.5 percent for adults aged 55 to 64. Nearly 25 percent of those aged 65 to 74 and 50 percent of those who are 75 and older have disabling hearing loss.⁶
• Roughly 10 percent of the U.S. adult population, or about 25 million Americans, has experienced tinnitus lasting at least five minutes in the past year.⁷
• About 28.8 million U.S. adults could benefit from using hearing aids.⁸
• Among adults aged 70 and older with hearing loss who could benefit from hearing aids, fewer than one in three (30 percent) has ever used them. Even fewer adults aged 20 to 69 (approximately 16 percent) who could benefit from wearing hearing aids have ever used them.⁹
• As of December 2012, approximately 324,200 cochlear implants have been implanted worldwide. In the United States, roughly 58,000 devices have been implanted in adults and 38,000 in children.¹⁰
• Five out of 6 children experience ear infection (otitis media) by the time they are 3 years old.¹¹
