There are a number of common causes of hearing loss, some which may be temporary blockages or abnormal growths, while others lead to permanent impairment because irreversible hearing damage has occurred.
It is crucial to recognise the differences rather than ignore the symptoms under the misapprehension that it’s probably due to a build-up of earwax!
To understand the vital difference it’s important to know the basic mechanism of how the ear works. Vibrating air molecules enter the outer ear and travel through the ear canal to activate the eardrum and the attached tiny bones in the middle ear.
Long-term exposure to continuous excessive loud noise is the chief cause of noise induced hearing loss, most commonly found in the workplace, and known as industrial deafness.
A sudden excessively loud noise – known as ‘acoustic trauma’ –creates a powerful sound wave which can rupture an eardrum or damage the inner ear. Other known types of physical damage result from severe head damage or trauma, which can dislocate middle-ear bones or cause nerve damage to cause permanent hearing loss, sudden changes in pressure when flying or water diving. Blockage of the ear canal are most commonly the build up of ear wax but can include noncancerous growths and tumours can grow in the inner ear. Some medicines are known to cause hearing loss as a potential side effect, which may include regular use of aspirin, types of antibiotics and cancer drugs.
Types of chronic diseases can cause hearing loss by interrupting blood flow to the inner ear or the brain, including heart disease, stroke, high blood pressure, and diabetes. Hearing weakens as a natural part of the aging process due to the progressive loss of inner-ear hair cells. Answer: About one in three Americans over 60 suffers from hearing loss, ranging from the inability to hear certain voices to deafness. Tinnitus, common in older people, is characterized by a ringing, hissing or roaring sound in the ears. Since your wife's hearing seems to be a problem, she should have it checked by her personal physician.


Another common cause of hearing loss is damage to the ear due to exposure to loud noises over time.
There are over 200 pharmaceuticals known to adversely affect the human auditory system.  Here are a few of the more common culprits. Not all problems with the auditory system are permanent.  Here is a list of a few causes of hearing loss that can in fact be treated. Severe head trauma can dislocate middle-ear bones or cause nerve damage, causing permanent hearing loss.
Noncancerous growths, including osteomas, exostoses, and benign polyps, can block the ear canal, causing hearing loss. The vibrations are relayed to fluid in the cochlea located in the inner ear where microscopic hairs send nerve signals via the auditory nerve to the brain where they are decoded into recognisable sounds. Over a period of time, the microscopic hairs in the cochlea of the inner ear are no longer able to function under the constant excessive bombardment and are permanently damaged. Conditions such as tinnitus, heard as a ringing, whistling or rushing in the ears can be the prolonged after effect – from hours or weeks to permanently – is typically caused by exposure to excessive noise levels at rock music venues, as well as constant exposure to noisy machinery, tools or vehicles within the workplace.
While it won't restore normal hearing, it will increase her awareness of sounds and what made them. If her hearing has diminished, the doctor will probably refer her to an otolaryngologist or audiologist. Using hand gestures and facial expressions will clue your wife in to what you're saying. Age-related hearing loss, or presbycusis, is the slow loss of hearing that occurs as people get older.  Most people begin to lose a small amount of their hearing beginning as early as age 30.
Sudden changes in pressure -- from flying or scuba diving -- can lead to damage to the eardrum, middle ear, or inner ear and hearing loss.
This causes the eardrum and tiny bones, called the hammer and anvil, in the middle ear to vibrate.
Ear infections can cause the middle ear to fill with fluid and cause hearing loss that usually clears when the infection and fluid are gone.


At any stage in the journey, if pathways are blocked or parts damaged, loss of hearing will be the result. Other causes include exposure to loud noise, heredity, head injury, infection, illness, certain prescription drugs and circulation problems such as high blood pressure. Before he began freelancing, he was a reporter, rewriteman and columnist for three daily newspapers in New Jersey: The Newark News, Newark Star-Ledger and Morristown Record. Then vibrations travel to the fluid in the cochlea where microscopic hairs send nerve signals to the brain so sound is understood.
Acoustic neuroma (an inner ear tumor shown here), grows on the hearing and balance nerve in the inner ear.
Though congenital hearing loss often runs in families, it can occur with maternal diabetes or an infection when pregnant. Usually, age-related hearing loss is caused by the progressive loss of inner-ear hair cells.
Autoimmune diseases, such as rheumatoid arthritis, also can be linked to some forms of hearing loss. The average decibel level at a rock show is 110, loud enough to cause permanent damage after just 15 minutes. Hearing damage can occur with extended exposure of any noise over 85 decibels. Diseases known to affect hearing in children include chickenpox, encephalitis, influenza, measles, meningitis, and mumps. 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.
Think you have an earwax blockage? Don't try removing the wax with a cotton-tipped swab or by inserting anything else into your ear canal. And if the inner ear is too damaged, even large vibrations will not be converted into signals.
