What is hearing loss?

Hearing loss refers to a decreased ability to hear. The loss of hearing can be partial or total. Treatment can improve hearing in some cases, but the hearing loss cannot usually be cured.

What are the two most common causes of hearing loss in adults?

The most common causes of hearing loss in adults are aging and exposure to noise.

Age-related hearing loss happens to a lot of people as they age and it can be mild or severe. Changes in the ear as we get older impact hearing. The outer part of the ear canal thins, and the eardrum may thicken. Earwax becomes drier and stickier which can result in impacted earwax. The part of the ear called the cochlea loses sensory cells, while nerve fibers that carry sound information to the brain degenerate.

Hearing loss that is caused by noise can occur suddenly or gradually over time. Sudden hearing loss from noise can occur from gunfire or explosions, and is a main cause of combat disability. Hearing loss that occurs over time can come from regular exposure to daily loud noises, such as a loud workplace, loud music, or using heavy machinery.

Genetics and diseases Medications and heart disease Noise and aging Ear disorders and allergies

About 48 million American suffer with hearing loss.

Hearing loss is the third-most common public health issue after arthritis and heart disease.

What are types of hearing loss?

There are 3 main types of hearing loss. The ear is made up of the outer ear, the middle ear, and the inner ear. The types of hearing loss

- Conductive hearing loss occurs when sounds cannot get through the outer ear (ear canal) and middle ear (ear drum, and the bones of the middle ear) to the inner ear. Soft sounds may be difficult to hear, and louder sounds may be muffled.
- Sensorineural hearing loss (SNHL) occurs when there is damage to the inner ear. This is also called nerve-related hearing loss and is the most common type of permanent hearing loss.
- Mixed hearing loss occurs when conductive hearing loss and sensorineural hearing loss occur at the same time.

Conductive hearing loss Sensorineural hearing loss Mixed hearing loss All of the above

Hearing loss is only treated with hearing aids.

Once hearing loss occurs, it can be treated but in most cases the hearing loss is permanent. Hearing aids are the most common treatment to restore hearing. In some cases cochlear implants and surgery may cure conductive hearing loss. Other treatments for hearing loss involve learning to cope with the condition, such as learning sign language or lip reading to help communicate.

Only people with serious hearing loss need hearing aids.

A hearing aid is a small electronic device that makes some sounds louder and is worn in or behind the ear. The Hearing Loss Association of America estimates that 80% of people with hearing loss who could benefit from a hearing aid don't wear one.

Hearing aids can help people with hearing loss to better communicate. The need for a hearing aid is based on the degree of hearing loss, and a person's need to hear the sounds around them. Certain professions, such as teachers or psychologists, need to hear to do their jobs. Other people may not work or socialize much, and may live in quiet rural areas so a small degree of hearing loss is tolerable. Talk to your doctor if you are experiencing any signs of hearing loss to learn more about hearing aids and other options.
