The different causes of hearing loss have not been the subject of systematic studies, but, generally speaking, meningitis, measles, otitis media and different febrile illnesses such as bacterial infections are the major causes of childhood hearing loss. In Nigeria a study found that 25 per cent of the cases of deafness can be linked to meningitis. Furthermore, a group of researchers who conducted a study in Sierra Leone found that otitis media commonly causes mild to moderate hearing loss. Hearing loss caused by genetic disorders may also play a roll but very little information exists about these factors due to a lack of trained personnel.

Tests using a tuning fork can check if there is damage to the parts of the middle ear and eardrum that vibrate. Autoimmune diseases, such as rheumatoid arthritis, also can be linked to some forms of hearing loss. How You Hear -- Anatomy of the EarSound waves enter the outer ear and travel through the ear canal. This causes the eardrum and tiny bones, called the hammer and anvil, in the middle ear to vibrate.
Then vibrations travel to the fluid in the cochlea where microscopic hairs send nerve signals to the brain so sound is understood.

Tumors and GrowthsNoncancerous growths, including osteomas, exostoses, and benign polyps, can block the ear canal, causing hearing loss. Acoustic neuroma (an inner ear tumor shown here), grows on the hearing and balance nerve in the inner ear.
However, the doctor will try to identify the cause of your hearing loss before treatment can begin.

Hearing loss can also develop if a newborn is premature or from other causes such as trauma during birth resulting in the infant not getting enough oxygen. Usually, age-related hearing loss is caused by the progressive loss of inner-ear hair cells.
