Ongoing Exposure to Noise on the JobLong-term exposure to continuous loud noise can cause lasting hearing loss.

When the sound waves move the eardrum, these bones move and pass on the vibration to the much smaller oval shaped window of the cochlea (the bit that looks like a shell).
The cochlea has fluid in it, which moves due to the vibrations and bends hairs on the outside of cells lining the cochlea.
Some of these hair cells (the 'inner hair cells') create an electrical impulse (signal), which is sent along the auditory nerve to the brain. Most of the hair cells (the 'outer' ones), however, are like tiny muscle cells, which react to the vibrations in the fluid by trembling and shaking. When you really want to listen to something you tell your brain to concentrate on that sound. If your ears are healthy and are both working well, they can 'turn down' or 'tune out' other sounds while you concentrate on what you want to hear. With healthy ears you can choose what you want to listen to, but you can't choose what you hear. Some people have problems understanding what they are hearing because their ears don't work well and they don't hear all the sounds. They think that you select (choose) what you are going to hear and what you definitely don't want to hear! Do you pretend you haven't heard sometimes - especially when it is something you don't want to hear? Like every other part of your body, ears need looking after if they are going to work as well as they can. Sometimes your ears feel funny when you are on a plane, going through a tunnel or driving up hills.


We've provided this information to help you to understand important things about staying healthy and happy.
It is intended for general informational purposes only and does not address individual circumstances. The hammer is touching the ear drum so it shakes when the sound comes through, and the movement goes right through the anvil to the stirrup, which is touching the window of the cochlea. They work like high quality amplifiers and make the vibrations much stronger and clearer for the smaller number of inner hair cells.
If your outer hair cells have been damaged by too much loud noise, what you want to hear can get mixed up and smothered by the other sounds around. You need to let more air into the inside of your ear or let some out to balance the air pressure on each side of your ear drum.
This lets air through the Eustachian tube into the middle ear, your ears will feel like they go 'pop' and you will be able to hear normally again. However, if you feel sick or unhappy, it is important to tell your mum or dad, a teacher or another grown-up. It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health. Never ignore professional medical advice in seeking treatment because of something you have read on the WebMD Site. Injury or Pressure ChangesSevere head trauma can dislocate middle-ear bones or cause nerve damage, causing permanent hearing loss. Sudden changes in pressure -- from flying or scuba diving -- can lead to damage to the eardrum, middle ear, or inner ear and hearing loss.
Chronic DiseaseCertain chronic diseases that are not directly related to the ear can cause hearing loss.
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. 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. Headphones and EarbudsCan others hear the music and lyrics you’re listening to through earphones? 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.

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. Diseases known to affect hearing in children include chickenpox, encephalitis, influenza, measles, meningitis, and mumps. Though congenital hearing loss often runs in families, it can occur with maternal diabetes or an infection when pregnant. 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.
