Age-related deafness can be caused by exposure to noise or by an impairment of the ability of the tiny, bony structures of the middle ear. These small bones can become rigid and therefore less able to pass the sound vibrations from the outer ear to the inner ear.

The symptoms of age-related hearing loss are a decreased ability to hear speech clearly and hearing loss of sounds in certain ranges or frequencies. Similar speech sounds may become difficult to distinguish. Background noise can make this even more difficult. Because the hearing loss is usually gradual, friends and family may notice the hearing loss before the person with the hearing loss does.

Age-related deafness can affect one or both ears. If the age-related deafness affects one ear, the condition is described as unilateral. If the hearing loss affects both ears, it is called bilateral hearing loss. Unilateral hearing loss can make it difficult for the person to identify the source of sounds.

The severity of the age-related deafness is measured by a hearing test. A person may have lost the ability to hear sounds beneath the threshold determined by the hearing loss. The louder the threshold of the person’s hearing ability, the more severe the hearing loss is. If someone has lost the ability to hear high-frequency sounds, the hearing loss may be called high-frequency hearing loss.

Tinnitus may also be a symptom of age-related hearing loss. Tinnitus us hearing sounds like ringing, buzzing, or crackling that are not present in the person’s environment.

Hearing aids are a common treatment for age-related hearing loss. The hearing aids amplify sound so that the person can hear better. Many types of hearing aids are available and many can be personalized to meet the specific needs of the individual. Hearing aids may also help reduce the presence of tinnitus.

Noise-induced hearing loss can occur suddenly due to a loud noise, also called auditory trauma. Examples of an auditory trauma are noises from an explosion, firecrackers, or gunshot. Sometimes, the trauma caused by an explosion or other sudden loud noise causes deafness that is not due to the noise itself, but due to the sudden change in air pressure. Auditory trauma can rupture the eardrum. A perforated eardrum often heals without medical treatment. Severe cases may need to be surgically repaired.

Hearing loss from noise rarely happens suddenly. Usually, there is a gradual loss of hearing. Noise-Induced hearing loss can also occur gradually due to lifetime exposure to noise. Age-related hearing loss is a gradual decrease in hearing ability often due to lifelong noise exposure.

Industrial hearing loss is noise-induced hearing loss caused by noise in an industrial setting. This type of hearing loss is most common in people who work in industrial settings with excessive noise. Protective gear such as earplugs are strongly recommended to protect the hearing of people who work in noisy environments.

Workers in other fields are at risk of noise-induced hearing loss. Occupational hearing loss is common among firefighters and musicians. Some manufacturing settings have excessive noise that can put the workers at risk for hearing loss.

Some people may not realize the danger of loud noise. Loud music as is common at rock concerts has been known to cause hearing loss. Considering that even a long exposure to normal noise levels can cause age-related hearing loss, habits or activities that cause exposure to loud noise can increase the risk or severity of the hearing loss that the person may experience later in life. The onset of hearing loss in someone who participates in activities in a noisy environment can be sooner than the onset of common age-related hearing loss.

Deafness from disease can happen any time during life, even before birth. Deafness can result from being exposed to rubella, influenza, or mumps before birth. Rubella is German measles. After birth, a severe cause of jaundice can put the baby at risk of hearing loss.

Some diseases classified as childhood diseases can cause deafness or hearing loss. Deafness from diseases of childhood can usually be prevented with proper vaccinations, however, this type of deafness remains fairly common in developing countries. Meningitis, mumps, cytomegalovirus, and chicken pox are examples of diseases that can cause deafness. Meningitis causes deafness if the inflammation around the brain causes the inner ear to also become inflamed.

Cytomegalovirus (CMV) is a virus that can be passed from mother to newborn during birth. CMV can cause progressive, permanent hearing loss. The extra mucus from the common cold can also cause temporary hearing loss. Fevers can be a cause deafness from disease.

Ear infections are the most common causes of hearing loss in children. A middle ear infection may cause muffled hearing in the effected ear. The hearing loss can become more severe and permanent if the ear infection is left untreated. Swimmer’s ear, also called an external ear infection, can cause temporary hearing loss due to swelling of the ear canal.

Otosclerosis is a disease of the ear that causes bony projections to develop. These growths can interfere with hearing. Otosclerosis can affect the middle ear, inner ear, or both.

Rheumatoid arthritis, lupus, and other autoimmune disorders have been associated with a risk of hearing loss. With these autoimmune diseases, hearing loss occurs if the immune system attacks the cells of the cochlea. Demyelinating diseases like MS can cause deafness.

Diabetes can cause hearing loss or deafness if the nerves or the blood supply of the ears is compromised. Nerve damage and damage to the circulatory system are symptoms of diabetes.

A perforated eardrum can be caused by inserting something into the ear canal or even by a loud, sudden noise. Ruptured eardrums due to a loud noise is said to be caused by auditory trauma. With some instances of loud noises causing deafness such as near an explosion, the sound may not be the cause the hearing loss. The hearing loss may be due to the sudden change in air pressure. Perforated eardrums often heal on their own without medical treatment. If there is considerable damage to the eardrum, surgery may be required to fix the eardrum.

A fractured skull can damage the structure of the ear and cause hearing loss. The ear has many tiny structures that are necessary for normal hearing. If these structures become damaged, hearing loss or deafness is likely. In some cases, the damage can be surgically repaired.

Head trauma can sometimes cause the jaw to become misaligned. This misalignment can cause temporomandibular joint disorder, commonly called TMJ or lockjaw. TMJ can cause hearing loss by interfering with the functioning of the Eustachian tubes or damage to the nerves of the ear.

Trauma is a possible cause of Meniere’s disease. Meniere’s disease is caused by a fluctuation in the amount of fluid in the inner ear. The inner ear is normally filled with fluid. A change in the level of fluid impairs hearing. Meniere’s disease can also impair the person’s sense of balance. This condition can also cause dizziness and tinnitus, or ringing in the ear. There is no cure for Meniere’s disease.

Injury to the cochlea or auditory nerve can cause sensorineural hearing loss. Injury to the inner ear can result from head trauma from car accidents or fights. This type of hearing loss is not able to be repaired surgically.

There are two ways of becoming deaf due to noise. How you become deaf from sudden noise is if the noise ruptures the eardrum. This type of deafness is usually temporary. A perforated eardrum heals naturally unless the damage is severe. The other way to become deaf from noise is through long-term exposure. The noise-induced deafness may occur from normal noise throughout one’s lifetime or from prolonged exposure to a noisy environment like working in an industrial setting.

Age-related deafness can be caused from noise exposure of a change in the flexibility of the bony structures of the ear. Age-related deafness is a common condition called presbycusis.

Exposure to certain diseases can cause deafness. Rubella, influenza, mumps, and meningitis can cause deafness. There are also diseases of the ear that can cause hearing loss or deafness. Otosclerosis is a disease of the ear characterized by growths in the middle ear, inner ear, or both. Otosclerosis can cause deafness.

Ear infections, if left untreated, can cause deafness or hearing loss. Severe ear infections are the most common cause of deafness that develops during childhood. If promptly treated, ear infections rarely cause permanent hearing loss.

Trauma can cause deafness if the trauma damages the ear. Skull fractures, blows to the head, or blows to the ear could damage the structure of the ear and cause deafness. Swelling of the brain due to head trauma can cause the pressure of the swelling to damage the ear.

Exposure to some environmental toxins causes deafness. Some medications can cause deafness by damaging the inner ear. Deafness or hearing loss from toxic substances or medications is called ear poisoning or ototoxicity.

The cause of the deafness is often unidentified. Idiopathic hearing loss is hearing loss for which the cause is unknown. Sudden hearing loss is often idiopathic.

This condition can cause hearing loss, deafness, and problems in maintaining balance and posture. Ear poisoning can also cause tinnitus. Tinnitus is hearing a sound that is not there. The sound could be ringing in the ear or a variety of other sounds. The symptoms of ototoxicity may be temporary or permanent. The person may develop symptoms of ear poisoning after one exposure or after prolonged exposure to the toxin.

Many different medications can cause hearing loss. Loop diuretics, aminoglycoside antibiotics, and even aspirin can be a cause of ototoxicity. Quinine is an anti-malaria medication that can cause ototoxicity. Some cancer-treating drugs have a risk of ototoxicity. Hearing loss due to medications is often temporary. People should not stop taking prescribed medication before discussing the risk of ear poisoning with their doctors.

Exposure to chemicals that can cause hearing loss often causes permanent damage. Carbon monoxide, mercury, carbon disulfide, manganese, tin, and lead are examples of substances that pose a risk of ototoxicity. Exposure to these substances can cause permanent hearing loss and permanent impairment of balance.

When the patient experiences hearing loss, the physician will ask a series of questions regarding the onset of the hearing loss and exposure to any substances that can cause ear poisoning. There is no specific test for ototoxicity. The diagnosis of ototoxicity is based on the patient’s history of exposure to possible causes and by ruling out other possible causes of hearing loss.

There is no cure for permanent damage caused by ototoxicity. Treatment is focused on decreasing the symptoms and helping patients cope with the hearing loss or other symptoms. Hearing aids and cochlear implants are sometimes used as part of the treatment for ear poisoning. Physical therapy is sometimes used to treat balance impairments due to ototoxicity.

The frequency of congenital deafness is approximately one out of every one or two thousand births. Bilateral hearing loss is hearing loss affecting both ears. Unilateral hearing loss only affects one ear. Bilateral congenital hearing loss is more common than unilateral congenital hearing loss.

Congenital deafness can be caused by a heredity, genetic condition, or deformity of the ear. Genetic deafness through the normal heredity of genes is the most common cause of congenital deafness. The parents who are deaf or carry recessive genes that cause deafness have a high risk of having infants with genetic deafness. The deafness may have been passed down through numerous generations of the family.

Not all genetic hearing loss is inherited from the parents. Mutations of the genes can cause a syndrome that was not inherited from the parents. About twenty percent of congenital hearing loss is caused by syndromes caused by genetic mutations or gene abnormalities.

The genetic syndromes that can cause deafness are usually unexpected. Families of children born with these syndromes rarely have any other children with that syndrome in the family’s medical history. Many of these non-hereditary syndromes cause several birth defects including hearing loss or deafness. Usher syndrome, CHARGE syndrome, Mohr-Tranebjaerg syndrome, Jervell and Lange-Nielsen Syndrome, and Waardenburg syndrome are examples of syndromes that can cause congenital hearing loss.

Numerous hospitals across the world routinely test newborns for hearing loss. If the infant has not had a hearing screening or the test failed to detect a congenital hearing loss, a hearing loss may be suspected if the infant has a pattern of failing to react to auditory stimuli. Infants have a natural startle reflex which causes jerky movement in reaction to loud noise. The absence of the startle reflex can mean that the infant is not hearing noise that would otherwise cause the startle reflex.

Congenital hearing loss can be caused by a genetic condition or deformity of the ear. The most common form of congenital deafness is through heredity. The parents may carry dominant or recessive genes that cause deafness. In these cases, the families may have passed deafness down through numerous generations.

Not all genetic causes of congenital deafness are inherited from the parents. Genes can mutate and cause a syndrome that was not passed down by the parents. Only twenty percent of congenital deafness is caused by syndromes. Families of children born with these syndromes may not have had any other instances of that syndrome in the family.

Many of these non-hereditary syndromes cause several birth defects including hearing loss or deafness. CHARGE syndrome is one condition that is caused by a genetic mutation. CHARGE syndrome causes many birth defects, one of which is congenital hearing loss. Mohr-Tranebjaerg syndrome, Jervell and Lange-Nielsen Syndrome, Usher syndrome and Waardenburg syndrome are other examples of syndromes that can cause congenital hearing loss.

Non-inherited causes of congenital deafness are malformations of parts of the ear. The Mondini malformation causes about twenty percent of congenital sensorineural deafness. Mondini malformation results in a misshapen cochlea.

Congenital hearing loss may not be immediately apparent in newborns. Many hospitals across the world screen newborns for hearing loss. If the infant has not had a hearing test or the test failed to detect a congenital hearing loss, a pattern of failure to respond to auditory stimuli can suggest that there might be a problem with the infant’s hearing. Infants with normal hearing have a natural startle reflex in reaction to loud noise. The absence of this reflex can mean that the infant is not hearing noise that would otherwise set off the startle reflex.

The sudden hearing loss is most commonly noticed upon waking in the morning. The person may not notice the hearing loss until they attempt to use the affected ear such as while making a phone call. In addition to the hearing loss, people with sudden hearing loss syndrome may have a ringing in the ears or dizziness. The ringing in the ears is called tinnitus and may involve a variety of different, repetitive sounds or tones, not just ringing.

A sudden loss of hearing should be considered a medical emergency. Prompt medical attention increases the chance that the hearing can be treated or at least partially restored. There are numerous possible causes of sudden hearing loss. Some possible causes of sudden hearing loss are disease, lack of oxygen, tumors, poisoning, and head trauma. In most cases, the cause is never identified. Therefore, it may be described as idiopathic.

A physician can measure the hearing loss with a hearing test. Sudden hearing loss syndrome is characterized by a loss of hearing of thirty decibels. The thirty decibel level is half as loud as normal conversation. A person with sudden hearing loss syndrome has lost the ability to hear any sound below this level.

The standard treatment for sudden hearing loss syndrome is the administration of steroids. If a specific cause has been determined, the physician may be able to tailor the treatment to the cause. However, there is substantial debate over the best treatment for many causes of sudden deafness. Therefore, steroids remain the most common treatment. A low-salt diet may also be recommended for patients with sudden hearing loss syndrome.

Some cases of sudden deafness resolve on their own without medical treatment. This is called spontaneous recovery. When the person recovers their hearing without medical treatment, it usually occurs within three days.

The degree of hearing loss is often referred to as the severity of the hearing loss. The hearing loss may be mild and cause muffling of sound. Mild hearing loss can be problematic in environments with background noise. Such hearing loss is common in people of advanced age. More severe hearing loss can greatly impair someone’s ability to hear.

Hearing loss can affect one ear or both ears. Hearing loss that affects one ear is called unilateral hearing loss. Symptoms of unilateral hearing loss include an inability to hear sounds on that side and difficulty identifying the source of sound. Hearing loss of both ears is called bilateral hearing loss.

Other symptoms of deafness can include dizziness, called vertigo, and tinnitus. The condition of tinnitus is characterized by hearing sounds that are not in the person’s environment. The person may hear a ringing in the ears or a repetitive noise or tone. A wide variety of sounds are reported by people with tinnitus.

There are emotional symptoms of hearing impairment. People with hearing loss may be irritable due to frustration of not being able to hear clearly. They may become isolated and tire of social interaction due to not being able to understand conversations and aggravation over having to ask people to repeat themselves. Social isolation is considered a common symptom of hearing impairment in children who may feel different from children who can hear normally.

Depression is sometimes reported as a symptom of deafness. This can be especially true if the person can no longer enjoy auditory activities that they once enjoyed such as music or watching television. Many times, the use of a hearing aid can help a person enjoy the activities that they could when they could hear normally.
