Hearing loss


Decreased hearing; Deafness; Loss of hearing; Conductive hearing loss; Sensorineural hearing loss; Presbycusis

Hearing loss is being partly or totally unable to hear sound in one or both ears.

I Would Like to Learn About:

  • Considerations

    Symptoms of hearing loss may include:

    • Certain sounds seeming too loud
    • Difficulty following conversations when two or more people are talking
    • Difficulty hearing in noisy areas
    • Trouble telling high-pitched sounds (such as "s" or "th") from one another
    • Less trouble hearing men's voices than women's voices
    • Problems hearing when there is background noise
    • Hearing voices as mumbled or slurred

    Other symptoms include:

    • Feeling of being off-balance or dizzy (more common with Ménière's disease and acoustic neuroma)
    • Feeling of pressure in the ear (in the fluid behind the eardrum)
    • Ringing or buzzing sound in the ears (tinnitus)
  • Causes

    Conductive hearing loss (CHL) occurs because of a mechanical problem in the outer or middle ear. This may be because:

    • The three tiny bones of the ear (ossicles) are not conducting sound properly.
    • The eardrum is not vibrating in response to sound.

    Causes of conductive hearing loss can often be treated. They include:

    • Buildup of wax in the ear canal
    • Damage to the very small bones (ossicles) that are right behind the eardrum
    • Fluid remaining in the ear after an ear infection
    • Foreign object that is stuck in the ear canal
    • Hole in the eardrum
    • Scar on the eardrum from repeat infections

    Sensorineural hearing loss (SNHL) occurs when the tiny hair cells (nerve endings) that detect sound in the ear are injured, diseased, do not work correctly, or have died. This type of hearing loss often cannot be reversed.

    Sensorineural hearing loss is commonly caused by:

    • Acoustic neuroma
    • Age-related hearing loss
    • Childhood infections, such as meningitis, mumps, scarlet fever, and measles
    • Ménière'
    • Regular exposure to loud noises (such as from work or recreation)
    • Use of certain medicines

    Hearing loss may be present at birth (congenital) and can be due to:

    • Birth defects that cause changes in the ear structures
    • Genetic conditions (more than 400 are known)
    • Infections the mother passes to her baby in the womb (such as toxoplasmosis, rubella, or herpes

    The ear can also be injured by:

  • Home Care

    You can often flush wax buildup out of the ear (gently) with ear syringes (available in drug stores) and warm water. Wax softeners (like Cerumenex) may be needed if the wax is hard and stuck in the ear.

    Take care when removing foreign objects from the ear. Unless it is easy to get to, have your health care provider remove the object. Don't use sharp instruments to remove foreign objects.

    See your health care provider for any other hearing loss.

  • When to Contact a Medical Professional

    Call your health care provider if:

    • Hearing problems interfere with your lifestyle.
    • Hearing problems do not go away or become worse.
    • The hearing is worse in one ear than the other.
    • You have sudden, severe hearing loss or ringing in the ears (tinnitus).
    • You have other symptoms, such as ear pain, along with hearing problems.
    • You have new headaches, weakness, or numbness anywhere on your body.
  • What to Expect at Your Office Visit

    The health care provider will take your medical history and do a physical exam.

    Tests that may be done include:

    • Audiometry (a hearing test used to check the type and amount of hearing loss)
    • CT or MRI scan of the head (if a tumor or fracture is suspected)
    • Tympanometry

    The following surgeries may help some types of hearing loss:

    • Eardrum repair
    • Placing tubes in the eardrums to remove fluid
    • Repair of the small bones in the middle ear (ossiculoplasty)

    The following may help with long-term hearing loss:

    Cochlear implants are only used in people who have lost too much hearing to benefit from a hearing aid.
