One major explanation given is the insurgency's use of a fearsome weapon the Pentagon did not fully anticipate: powerful roadside bombs. Also, much of the fighting consists of ambushes, bombings and firefights, which come suddenly and unexpectedly, giving soldiers no time to use their military-issued hearing protection.
In addition, some servicemen on patrol refuse to wear earplugs for fear of dulling their senses and missing sounds that can make the difference between life and death, Hoffer and others said. Hearing damage has been a battlefield risk ever since the introduction of explosives and artillery, and the U.S. The military has responded over the past three years with better and easier-to-use earplugs, greater efforts to educate troops about protecting their hearing, and more testing in the war zone to detect ear injuries. The results aren't in yet on the new measures, but Army officials believe they will significantly slow the rate of new cases of hearing damage, said Col.
Rates of women who are opting for preventive mastectomies, such as Angeline Jolie, have increased by an estimated 50 percent in recent years, experts say. The number of servicemen and servicewomen on disability because of hearing damage is expected to grow 18 percent a year, with payments totaling $1.1 billion annually by 2011, according to an analysis of VA data by the American Tinnitus Association. Given today's fearsome weaponry, even the best hearing protection is only partly effective — and only if it's properly used.
Some Marines were issued a $7.40 pair of double-sided earplugs, with one side designed to protect from weapons fire and explosions, the other from aircraft and tank noise. The Navy and Marines have begun buying and distributing state-of-the-art earplugs, known as QuietPro, that contain digital processors that block out damaging sound waves from gunshots and explosions and still allow users to hear everyday noises. The Army also has equipped every soldier being sent to Iraq and Afghanistan with newly developed one-sided earplugs that cost about $8.50, and it has begun testing QuietPro with some troops.
In addition, the Navy is working with San Diego-based American BioHealth Group to develop a "hearing pill" that could protect troops' ears.
And for the first time in American warfare, for the past three years, hearing specialists or hearing-trained medics have been put on the front lines instead of just at field hospitals, Hoffer said.
Marines and soldiers are getting hearing tests before going on patrol and when they return to base if they were exposed to bombs or gunfire.
It is always best to conserve the hearing that we have, which is why we offer custom molded ear plugs in many different styles.
The causes of Noise Induced Hearing Loss include environmental noise, recreational activities, music and toys that exceed safe levels of sound. The number of reported cases of Noise Induced Hearing Loss has doubled in the last 30 years.
Listening to hazardously loud levels of sound for even short periods of time increases your chance of developing the irreversible effects of hearing loss. Noise Induced Hearing Loss causes include music, toys, recreational activities and environmental noise that exceed safe sound levels. Setting a safe volume limit for your iPad or iPod is important because it reduces your risk of developing irreversible Noise Induced Hearing Loss (NIHL). Extended exposure to sounds over 85 decibels can cause hearing damage and your iPad or iPod can produce sounds over 105 decibels! Check the chart below to see how long and how loud you can listen to your iPod before you reach hazardous levels of sound.
Click on your iPod model below for a video example on how to set the volume limiter to 70% of the maximum volume. If you listen to your iPad or iPod at high volumes, even for short periods of time, you have increased your risk of developing Noise Induced Hearing Loss (NIHL).
We all know somebody affected by hearing loss, as nearly 1 in 5 people live with the condition. Quality of life can be significantly compromised for people with hearing problems and their families. In contradiction to many people's understanding, hearing loss is rarely similar to the effect of turning down the volume on a stereo. If you feel that your hearing is not what it used to be, or are concerned that a loved one may be experiencing hearing loss take a couple of minutes to do our online hearing tests.
However, conductive loss accounts for only 10% of all hearing losses, and they range from mild to moderate in severity. When volume is sufficiently increased, clarity and understanding are usually intact for someone with a conductive hearing loss. Hearing loss that originates in the inner ear is referred to as sensorineural hearing loss or, less technically, nerve deafness. In more than 95% of cases involving sensorineural hearing loss, hearing aids or cochlear implants are the recommended course of treatment. While the overall volume of sound may be reduced, the clarity of sounds or voices is also affected.
Given the impact of noise, it is not surprising that males are considerably more likely to have hearing loss than women including being twice as likely to have a moderate to severe hearing loss.


The chart to the right illustrates the time it takes to cause permanent damage to your hearing when you're exposed to different levels and sources of sound.
While the ageing process is a major contributor to hearing loss, it is certainly not a condition reserved for the later stages of life. Interestingly, around 50% of people with hearing loss are still of traditional working age (i.e. Nerves have different sensitivities to deformation of the sensory hair cells within the cochlea. Over time the high pitch hair cell receptors receive more movement by the incoming pressure waves of the fluid inside the cochlea.
With the advancement of medical science over the last few decades, one would think that we would be abe to explain the reasons for each individual's hearing loss, unfortunately this is not the case. Conductive Hearing Loss occurs when there is a problem in the outer ear or the middle ear, such as ear wax, fluid behind the eardrum, or middle ear infection.
Although hi-fi speakers can be turned up to ear damaging levels, they have the advantage of not being strapped directly to your ear canal.
Private listening sessions on headphones and earbuds can be enjoyable, but you must excersice caution not to listen too loudly. Indoors in a quiet listening environment: According to the Airo study, listeners in a quiet room set headphone volumes at an average of 69 dB, a little less than the average sound level in a restaurant. Hearing ProtectionOur hearing is an integral tool used for communication, balance, and localization. Another option is to use AUDIO-CD Hearing Test, a self-administered hearing test designed for home use. 1 disability in the war on terror, according to the Department of Veterans Affairs, and some experts say the true toll could take decades to become clear. Their blasts cause violent changes in air pressure that can rupture the eardrum and break bones inside the ear. Others were not given earplugs or did not take them along when they were sent into the war zone.
But many doctors are puzzled because the operation doesn't carry a 100 percent guarantee, it's major surgery -- and women have other options, from a once-a-day pill to careful monitoring.
Ryan Kelly, 27, of Austin, Texas, the noise of war is still with him more than four years after the simultaneous explosion of three roadside bombs near Baghdad. But the Marines were not given instructions in how to use the earplugs, and some cut them in half, while others used the wrong sides, making the devices virtually useless, Hoffer said. While damage can occur at 80 to 85 decibels — the noise level of a moving tank — the best protection cuts that by only 20 to 25 decibels. An early study in 2003 on 566 recruits showed a 25 to 27 percent reduction in permanent hearing loss. This number will increase in the future as the first generation with iPods begin to experience the early and irreversible signs of hearing damage as a result of their headphone habits. That's why you should limit your exposure to dangerous levels of sound by setting your iPad or iPod Volume Limiter and be aware of how long you listen.
The extent of the hearing loss varies too, from a mild to a profound hearing loss where loud safety signals may not be heard. Other symptoms may also be present, such as ear pain, drainage from the ears, or a feeling of pressure or a blockage. People with sensorineural hearing loss will often hear people speaking, but can't always understand all the words, even when the volume is adequate. This is illustrated through mandatory provision of ear protection on work sites and within factories.
Studies have shown that exposure to noise is thought to be a contributing factor in around 37% of cases of the condition. A sound that has high pitch will excite receptor cells near the opening of the cochlea, while a sound mostly containing low pitch will stimulate cells at the end of the cochlea. For this reason, high pitch receptors are more prone to long term damage than the low pitch hair cell receptors, which are more protected further up the cochlea.
Almost half are under the age of 65 and 54% of the population over the age of 65 suffer from hearing loss. Many times this type of hearing loss may be corrected by medical or surgical treatments.Symptoms of Hearing Loss. Even more, speakers produce sound that travels through the air before it reaches your ears. With open-air headphones, the ability to hear normal conversation through the headphones is a good indicator that the volume level is safe. In the Airo study, when the outdoor noise was a mere 65 dB, listeners raised headphone volume levels to over 80 dB. The test is performed over a range of 24 frequencies -- from 20 Hz, the lowest frequency humans can hear, to 20,000 Hz, the highest frequency humans can hear.


Ryan Kahlor listens for sounds as his hearing is tested at Balboa Navy Medical Center in San Diego, Feb. Nearly 70,000 of the more than 1.3 million troops who have served in the two war zones are collecting disability for tinnitus, a potentially debilitating ringing in the ears, and more than 58,000 are on disability for hearing loss, the VA said.
And some Marines weren't told how to use their specialized earplugs and inserted them incorrectly. But the sheer number of injuries and their nature — particularly the high incidence of tinnitus — came as a surprise to military medical specialists and outside experts. What I remember was my ears ringing," said Kelly, whose leg was blown off below the knee in 2003. The hearing damage ranges from mild, such as an inability to hear whispers or low pitches, to severe, including total deafness or a constant loud ringing that destroys the ability to concentrate.
That is not enough to protect the ears against an explosion or a firefight, which can range upwards of 183 decibels, said Dr.
More commonly it manifests as difficulty understanding speech, particularly in the presence of background noise. This can lead to conversations being difficult to follow particularly in noisy environments where competing background noise scrambles speech and conversations.
Therefore, 90% of hearing losses cannot be cured.A sensorineural hearing loss can be of any degree - mild, moderate, severe or profound.
An example of a mixed hearing loss may be someone with inner ear damage due to exposure to noise in their workplace over many years, who also currently has an infection that has led to a fluid build up in the middle ear. Nevertheless, every day millions of people are exposing themselves to noise levels that will surely lead to long-term damage to their hearing, including the use of personal stereo systems.
Hearing loss is the third most common medical condition in our adult population, following only high blood pressure and arthritis.
With this type of hearing loss the hair cells in the inner ear (Cochlea) have become damaged or less effective. If you recognize any of the following symptoms of hearing loss, please contact one of our offices or your personal physician to have your hearing professionally evaluated. Since air is an excellent absorber of sound, the overall sound pressure level will be reduced before it hits your ear drum.
Because closed-ear headphones acoustically isolate the listener, normal conversation may not be audible when wearing these types of headphones. Therefore, on a busy street, levels would likely have to be dangerously high to drown out ambient noise - especially if open-air headphones are used.
An audiologist can advise you on hearing protection options to help maintain the longevity of your hearing.
World War II was a different kind of war, waged to a far greater extent by way of vast artillery barrages, bombing raids and epic tank battles.
Ben Balough, a Navy captain and chairman of otolaryngology at the Balboa Navy Medical Center in San Diego. Not surprisingly, being able to follow conversations is the single biggest reason that people seek our help. On average, once a person determines that they have a hearing loss, they wait over seven years before seeking assistance.The impact of a hearing loss can be far reaching and involve many aspects of one's life. Second, they passively (and sometimes actively) reduce sound from the surrounding environment.
Instead, a safe volume level may be set by moving one earcup off and comparing the level in other earcup with that of normal conversation. While the Airo study recommends not using headphones in such noisy conditions, if the listener insists on musical accompaniment outdoors, closed-ear headphones and canalphones that substantially attenuate ambient noise may allow for safer listening volumes. Hearing impaired individuals may have difficulty localizing sounds, understanding speech in busy environments, and participating in everyday normal conversations. But many of us use headphones and earbuds to block out the world, sometimes at unsafe volumes. While reducing unwanted noises is a welcome, directly injecting sound into your ear can pose some risks. This can lead to social isolation, confusion, frustration, tension, anger, stress and depression. Recent studies also indicate that untreated hearing loss negatively affects one's overall health, quality of life and happiness.Causes of Adult Hearing Loss.
