For more informationyou should do further research on fitting hearing aids.Most people suffer gradual hearing loss as they age. About 25 percent of American’s between the ages of 65 and 75 have some degree of hearing loss. There are two main factors of hearing loss. The first is heredity. The second is chronic exposure to loud noises. Working with heavy machinery or power tools without proper ear protection can contribute to hearing loss by increasing the natural wear and tear on your ears over time.
Hearing loss happens when your cochlea, a snail shaped structure in the inner ear, is damaged. Nerve cells in the cochlea can degenerate and the hairs on them can break or bend. This causes electrical signals to transmit less efficiently, resulting in hearing loss. Other causes of hearing loss include ear infection, waxy buildup, ruptured eardrums and abnormal bone growths or tumors.
If your hearing loss is caused by damage to the cochlea a hearing aid may help restore some function. While hearing aids are not for everyone they do help many people hear better.
A hearing aid is a small electronic device you wear in or behind your ear. It is made up of three basic parts, a microphone, an amplifier and a battery. The hearing aid works by amplifying the sounds you hear. This makes processing those sounds easier for the chochlea. The greater the damage to your inner ear, the more sounds must be amplified for you to hear them.
Before you buy a hearing aid you should be evaluated by a licensed physician to be sure that your type of hearing loss can be helped by a hearing aid. Various kinds of hearing aids are available. An audiologist certified by the American Speech-Language-Hearing can help you shop around and find the hearing aid that is best for you. You will even be able to test-wear the device before you commit to buying it.
As technology increases hearing aids are becoming more discrete. Most are flesh colored to blend into your ear. Many are very small, making them more comfortable to wear and less noticeable by others. Some fit entirely into your ear making them almost impossible for others to detect.
Hearing aids vary in cost depending on their size, features and sophistication. The cost of buying and replacing batteries also varies between hearing aid since different models use different types of batteries.
The cost of your visits to the doctor, hearing tests and all or part of your hearing aid may be covered by your private health care plan. Medicare does not cover hearing aids however Medicaid often helps pay for children’s hearing aids.

Impairments in hearing can happen in either frequency or intensity, or both. Hearing loss severity is based on how well a person can hear the frequencies or intensities most often associated with speech. Severity can be described as mild, moderate, severe, or profound. The term “deaf” is sometimes used to describe someone who has an approximately 90 dB or greater hearing loss or who cannot use hearing to process speech and language information, even with the use of hearing aids.



Causes of Hearing Loss



How you hear



Hearing occurs when sound waves reach the structures inside your ear, where the sound wave vibrations are converted into nerve signals that your brain recognizes as sound.



Middle ear fluid



Serious infections, such as meningitis



Head injury



Listening to very loud music, especially through headphones



Repeated exposure to loud sounds, such as machinery



Common causes of deafness in children include inherited conditions, infection during pregnancy, meningitis, head injury and glue ear.



Common temporary causes include earwax, infection, glue ear and foreign body obstruction.



Hearing Loss Symptoms



If hearing loss is sudden, it may be from trauma or a problem with blood circulation. A gradual onset is suggestive of other causes such as aging or a tumor.



Some people may have a hearing problem without realizing it. Others might think they have a problem, but are too embarrassed to tell their doctor, friends, or family. You can help identify a possible hearing problem by asking yourself some key questions and, if necessary, having your hearing checked by a doctor.



The first sign of a noise-induced hearing loss is not hearing high-pitched sounds, like the singing of birds, or not understanding speech when in a crowd or an area with a lot of background noise. If the damage goes on, hearing declines further, and lower pitched sounds become hard to understand.



Treatment of Hearing Loss



When a hearing aid does not give enough amplification, as with profound deafness, a cochlear implant – sometimes known as a bionic ear – may help.



This device transmits sound directly into the auditory nerve via electrodes which are surgically implanted into the cochlea. The results of a cochlear implant vary between people, and it is hard to tell how useful it will be before it is implanted.



Home Care



Wax build-up can frequently be flushed 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 impacted.



Care should be taken when removing foreign bodies. Unless it is easy to get to, have your health care provider remove the object. Don’t use sharp instruments to remove foreign bodies.



Hearing Loss Prevention



Protect your ears in the workplace. Specially designed earmuffs that resemble earphones can protect your ears by bringing most loud sounds down to an acceptable level. Foam, pre-formed, or custom-molded earplugs made of plastic or rubber also can effectively protect your ears from damaging noise.
