Introduction
Hearing loss, also known as hearing impairment, is a partial or full hearing defect. A deaf person heard something a little. Hearing loss can occur in either or both ears. Children’s hearing problems can affect the ability to learn a spoken language, while adults can face social interactions and workplace difficulties. In the case of some people, especially elderly people, hearing loss can lead to loneliness. Hearing loss may be temporary or permanent.
Symptoms of Hearing Loss
The symptoms of hearing loss may vary depending on the type of hearing loss, the cause of the hearing loss, and the degree of loss.
In general, people with hearing loss may have one or more of the following experiences:
It is difficult to understand everyday life
Feeling that you can hear but do not understand
TV or Radio must be running
Asking others to repeat themselves frequently
Avoid social situations that once were fun
More difficulty communicating in noisy situations such as restaurants, live family meetings, car or group workshops.
Tinnitus, ringing and/or bushy sounds in your ears.
Types of Hearing Loss
Perception of hearing loss
A constant hearing loss is the most common type of hearing loss. It is solid and causes or damages small hair, like cells in the inner ear or auditory nerve. The auditory nerve carries important information about the size, pitch, and significance of sounds in the brain. Most adults with loss of perception of hearing loss. Reliable hearing loss can often lead to problems with sound or speech understanding, although it can be heard loud enough.
Sequential Hearing Loss
Hearing loss is caused by mechanical problems in the outer or middle ear or in the disability of the ear canal, such as sulfur, which prevents the eardrum from escaping. It can be permanent, but more often it is temporary and can be treated as medically.
Mixed Hearing Loss
Mixed hearing loss results when both perception and conductivity loss.
Causes of hearing loss
The reason for some hearing loss is important to understand because it has factors that are difficult to determine proper treatment. There are many reasons for hearing loss and some causes are limited to the loss of certain types of hearing. For example, an ear wax that blocks the auditory canal, allows temporary wires to lose hearing and long-term exposure to excessive noise caused by permanent hearing loss.
Hearing loss can be caused by one of the following reasons:
Pre-Age (hearing loss related to age Presbycusis calls)
Some medicines also called “ototoxic ” Drugs
Trauma or head trauma
Genetic factors
A noise that is too loud
Acoustic Trauma in one episode
Some diseases, such as mumps, Meniere’s disease, otosclerosis or autoimmune disease
A tumor in the air of the nerve or neuroma acoustical.
Causes of severe hearing loss
Permanent acoustic contamination along the track
Long-term exposure to persistent noise can cause continuous hearing loss. The common culprit is noise-working, such as machinery. About 30 million Americans are exposed to dangerous noise levels in the workplace. Things like motorcycles and power tools can also gradually damage your hearing. If you do this, avoid or take a break from noisy activities. Wear the earbuds or headphones that match your ear.
Damage or changes in pressure
Serious head injuries can move in the middle ear bones or cause nerves, resulting in a continuous hearing loss. Sudden pressure from flies or dive sites can cause damage to the eardrum, middle ear or inner ear, and hearing loss. Earrings usually heal for several weeks. In severe cases of damage to the inner ear, it may be necessary surgery. Sticking cotton gifts or other objects in the ear is a bad idea. This can destroy the eardrum and cause permanent damage.
Hearing Tests
Anyone who suspects a hearing loss should contact a qualified hearing aid provider immediately. Hearing tests are simple, painless and widespread. Your health care professional will begin a comprehensive history and ask questions about problems, lifestyle and communication needs.
Otoacoustic Emissions Testing(OAE)
A fast, non-invasive probe measures the function of a cochlear (inner ear). In this test, a small probe is placed in the child’s ear and a click or famous replays and sent a probe speaker to the hearing aid channel, through the middle ear, and into the cochlea. The external cochlear hair cells are created and react, creating and emitting acoustic reactions. This remitted reaction then returns from the cochlea back to the ear canal, where it is detected by the probe microphone. It is certainly not what the child hears the test, it just tells the doctors if the hair cells of the ear work within normal limits.
Impedance Tests
These are tests that determine the middle ear function. It only takes 3 to 30 seconds per ear. This can also be referred to as a test simulation that tests, called (a) tympanometry, and (b) acoustic reflexes are used. This type of assessment allows the drum to be moved under different pressure conditions to determine whether there is a problem in the middle ear.
Auditory Brainstem Response (ABR6.4 Audiometry)
In this test, three small electrodes are placed on the baby’s head and then clicks or sounds are played by small earphones placed on the baby’s ears. A device to measure the brain’s response to these sounds. This test is not a tool what a child can hear, but will find brain sounds actively responsive to. This test lasts only a few minutes and can be performed while your baby sleeps.
Audiometry
Audiometry uses a sound-covered place where the child delivers different sounds from high to small places and soft intensity for loud. An Audiologist will give a child a response to different sound and document. A small child can be trained to turn into audio (behavioral tests), or a toy on the field or ring underneath (play audio metrics).
Treatments
Depends on the type and source of hearing loss. Rapid treatment of sudden hearing loss can increase your chances of recovery.
Surgery can cause hearing loss due to obnoklerosis, scarring or infection, while Ménière’s disease is sometimes treated with drugs and other diets.
Hearing loss caused by an infection can often be eliminated by antibiotics.
If you think your hearing loss comes from taking medicines, talk to your doctor about the possibilities of using medications.
Most people with permanent hearing loss can use a hearing aid. Usually, you can wear these little instruments or charge your ear that sounds louder. However, things sound different during the hearing, so you should speak to your doctor to set realistic goals.
Living with a hearing loss
First, set your house so that the rooms are well lit and the seat sits with you. When people say, watch their lips to move and their facial expressions.
Do not remove background noise. 9. Caring for Your EarsFor example, turn on your TV when nobody sees it.
Pay attention before starting the call.
Make sure you see your mouth in motion.
Speak clearly, but do not cry.
Caring for Your Ears
Hearing loss is often persistent, so do what you have to protect one of the most precious natural traits.
Headphones are worn when you’re there sounding loud or louder than movement. Mowers, electric grinders, vacuum pumps and most of the concerts are loud enough to damage unprotected ears. As far as possible, away from the source of a noise. For example, to go through the roadway or cover your ears while walking along the bustling road construction site.
If you work in a noisy workplace, talk to your employer about the safety of your ear. The National Institute for Safety and Health at Work (NIOSH) recommends that employers install obstructions on walls or silectors in noisy devices to protect their hearing.
