Hearing loss is usually caused by the dysfunction of the inner ear, auditory nerves, the cochlea, or due to brain damage. The hearing loss is usually due to impaired hair cells in the cochlea. Therefore, as individuals raise older, their hair cells lose few functions, and hearing gets worse. Therefore, there are multiple causes of hearing loss. It may be hereditary or due to the aging process. It can be activated by an explosion of loud noise, infections, the effects of poisons or may be due to injury.
The signs and symptoms of hearing loss may comprise:
The general causes of hearing loss include:
However, the hearing loss that happens progressively as you age (presbycusis) is common. So, around one-third of individuals in the United States between the ages of 65 and 75 have some grade of hearing loss. For older than 75 years, that number is almost 1 in 2.
Factors that may damage or lead to loss of the hairs and nerve cells in your inner ear include:
The deterioration of inner ear structures happens over time.
Exposure to the very loud sounds may also damage the cells of the inner ear. The damage may also happen with the long-term exposure to the very loud noises, or from a small blast of noise, such as from a firing.
The genetic history may make the person more vulnerable to ear harm from sound or worsening from aging.
The types of jobs where brash noise is a consistent part of the working setting, such as agri-business, production or factory work may lead to the destruction of the human ear.
The exposure to tense noises, such as from weapons and jet machines may cause instant, lasting hearing loss. Other recreational activities with hazardously high sound levels include snowmobiling, motorcycling, woodworking or attending to loud melody or concerts.
Many medications such as the antibiotic like gentamicin, sildenafil and certain chemotherapy medications may damage the inner ear. Momentary effects on the hearing i.e. ringing in the ear called tinnitus or hearing loss may happen if the person may take very high doses of aspirin, pain killers, antimalarial drugs or loop diuretics.
Many illnesses or infections that consequence in high-grade fever, such as in the case of meningitis, may harm the cochlea.
It is defined as one of three types:
The aging and chronic exposure to the loud noises both contribute to this problem of hearing. Other factors, such as excessive earwax, can momentarily decrease how well our ears conduct sounds.
It is not possible to reverse most types of hearing loss. However, a hearing expert can take steps to improve the hearing.
This is due to complications with the ear canal, ear-drum, or middle ear and its tiny bones i.e. the malleus, incus, and stapes.
The causes of Conductive Hearing Loss are
Surgery may correct the conductive hearing loss that is due to the congenital absence of ear canal or failure of the ear canal to be open at birth, congenital deficiency, deformity, and dysfunction of the middle ear structures.
This is due to difficulties of the inner ear, also called nerve-related hearing loss.
This is due to a combination of conductive impairment in the outer or middle ear and sensorineural injury in the inner ear i.e. cochlea or auditory nerve.
The human ear consist of three major areas:
The auditory nerve then carries these signals to the human brain through a series of steps.
Hearing loss can have a noteworthy effect on the human quality of life. The older adults with hearing loss problems may report the state of mind of despair. Because the problem of hearing loss can make chat difficult, many individuals may have feelings of Isolation.Hearing loss is also related the intellectual deficiency and deterioration.
The mechanism of interaction between hearing loss, intellectual weakening, despair and isolation is being vigorously deliberate. Latest research recommends that treating hearing loss can have an encouraging effect on cognitive performance, particularly memory.
The following steps can help prevent noise encouraged hearing loss and avoid deteriorating of age-linked hearing loss.
By limiting the duration and strength of exposure to noise is the greatest protection. In the place of work, plastic earplugs or glycerin-filled earmuffs can help defend the ears from harmful noise.
Try to consider regular hearing tests, if the person works in a loud setting. If the person lost some hearing, they must take steps to stop additional loss.
