Causes of hearing loss by type, including wax and noise buildup

Hearing loss is a common problem in many people.If you can not hear sound partially or in one of your ears, hearing loss usually occurs over time, depending on the American Institute of Deafness and Other Communication Disorders.NIDCDAbout 25% of people aged 65 to 74 are hearing-impaired, according to the siteHealth Line"He said.

How the audience works

The three main parts of the ear are the outer ear, the middle ear and the inner ear. The hearing begins when the sound waves pass through the outer ear to the eardrum, a thin piece of skin located between the outer ear and the middle ear.

The three bones of the middle ear are called ossicles, including the hammer, the anvil and the passengers. The eardrum and alkali work together to increase the vibrations when transmitting sound waves to the inner ear.

When the sound waves reach the inner ear, they pass through the fluids of the cochlea. The cochlea is a spiral structure located in the inner ear. In the cochlea, nerve cells are associated with thousands of tiny hairs. When your brain interprets these electrical signals as sounds, different vocal vibrations create different interactions in these small hairs, suggesting different sounds for your brain.

Causes of hearing loss

American Association of Audience and PronunciationASHAWith three main types of hearing loss, each due to different underlying factors, the three most common causes of hearing loss are hearing loss, sensory hearing loss.SNHL), And mixed hearing loss.

I. Transmission deafness

Conductive hearing loss occurs when sounds can not move from the outer ear to the eardrum and bones of the middle ear.When this type of hearing loss occurs, it can be difficult to hear. hear weak or muffled sounds.

The cochlear implant is a small electrical machine placed under the skin behind the ear that translates sound vibrations into electrical signals that can be interpreted by the patient. Your brain is a meaningful voice.

Transmission deafness can be the result of:

– ear infections.

– sensitivity.

– the swimmer's ear.

– The wax of ear is accumulated.

Any foreign object stuck in the ear, a benign tumor or a scar in the ear canal due to repeated infections are all possible causes of hearing loss.

II Sensory hearing loss (SNHL)

Happens SNHL When there is damage in the structures of the inner ear or in the nerve pathways of the brain, this type of hearing loss is usually permanent and the sound seems blurry.

Nerve loss can result from:

– Congenital defects that alter the structure of the ear.

– aging

– Work at high noise.

– Shock on the head or the skull.

Minor disease, an inner ear disorder that can affect hearing and balance.

Neuromuscular Nerve Tumor, a noncancerous tumor that develops on the nerve that refers to the ear in the brain and is called the vestibular cochlear nerve.

– Infection

The infection can damage the nerves of the ear and cause loss of hearing of sensory nerves, such as measles, meningitis, mumps, scarlet fever, certain medications known as "toxic drugs for the ears". A prescription that can cause hearing loss, and these drugs are drugs to treat cancer, heart disease or any serious infection.

III Mixed hearing loss

Mixed hearing loss can also occur when hearing and nerve loss occurs simultaneously.

Symptoms of hearing loss

– Hearing loss that interferes with your daily activities.

– Hearing loss that worsens or does not go away.

– worse hearing loss in one ear.

Sudden hearing loss.

– severe hearing loss.

– Pain in the ear and hearing problems.

– headache.

– numbness and weakness.
