When considering construction worker injuries many people think of examples of injuries caused by physical accidents from impacts such as a fall from a ladder or scaffolding. Construction workers are often exposed to loud noises which make them especially susceptible to the loss of hearing. Hazardous noise is defined as noise which exceeds 90bD (decibels) for an extended period of time. Compared to a 9 percent risk factor for no noise exposure, and a 30 percent risk in manufacturing, construction, along with mining, remain the top two high-risk professions in industry.
The most common cause of hearing loss on a job site is intuitive: a lack of use of protective hearing equipment, which is required by law.
First, the employer may not make them aware of the risks of working in an environment with hazardous noise and may not provide them with appropriate hearing protection.
Lack of equipment to control noise can be a contributing factor to hearing loss as can failing to take breaks when working in an area containing hazardous noise. Hearing loss typically occurs in areas where noise levels exceed 90bD – the established noise level that is deemed “hazardous” to workers’ hearing. Hearing loss usually does not occur upon a single overexposure, although if the noise is loud enough, it may permanently or temporarily cause hearing loss.
Workers who start young, and enjoy a lifetime of work in construction, may be at an increased risk for hearing loss, particularly if their exposure levels exceeded the maximum threshold during most workdays. Sensorineural hearing loss is a type of hearing loss which occurs because of some type of damage to the ear.
With repeated overexposure to hazardous noise, construction workers are most likely to be exposed to sensorineural hearing loss at some point during their lives. Severe hearing loss occurs when some loud sounds are inaudible and communication is impossible or extremely difficult without a hearing aid.
Working in environments where construction is going on represent an inherent danger, because the noise level often exceeds the 100dB level. Tinnitus is just one symptom that results from the damage and destruction of those hair cells. In addition to hearing loss, workers may experience nervousness, a reduced ability to concentrate, a reduction in the quality of sleep, an inability to get to sleep in a timely or efficient manner, reduced productivity, and an increased risk of work-related accidents.
Workers who lose their hearing are also more susceptible to feeling isolated and may have trouble communicating with co-workers. Passive protective devices or uniform-attenuating protectors use mechanical blocks or means to filter sounds to provide equal attenuation across the audible frequency range. The sounds heard with passive protection in place are more natural, clearer and less distorted than protection provided by low-quality alternative or conventional hearing protectors.
Some workers may have the tendency to only wear hearing protection when they are currently working, but may not wear the protection when they have finished the job but are still on the construction site in an area where hazardous noise exists. Active hearing protection or “level dependent” hearing protectors block sound and also use electronic means to transmit low-level sounds through the hearing protector.
Electronic devices also allow users control over the attenuation of hazardous noise, essentially allowing customization of hearing.
Another benefit of these devices is that special FM or infrared (wireless) capabilities can be integrated into the device to provide one or two-way communication. Again, for these devices to work, they must be properly fitted and worn during times when hazardous noise threatens the individual.
Periodic replacement and maintenance is necessary with these types of ear protectors, which makes them a more expensive option.
Cochlear implants have been approved by the Food and Drug Administration for children and adults who are deaf or severely hard-of-hearing. The implant itself consists of a microphone, which is capable of picking up sounds from the environment. Instead, they capture the sounds of the environment and convert them into electrical signals.
If you feel that the risks that you’re being asked to take are unreasonable, you’ve suffered hearing damage on the job, or if  you’ve been injured in some other way on a construction site, don’t hesitate to speak with an attorney.
The sound can’t reach the inner ear normally due to a problem with either the outer ear or the middle ear.
Some possible causes are wax build up, external and middle ear infections or other medical conditions. Some possible causes are exposition to loud noise, normal aging or other medical conditions. The effects of a sensorineural hearing loss and sometimes of a permanent conductive hearing loss may be diminished with the use of hearing aids.
Some other equipment may help people with a hearing loss such has amplified telephones and personal amplification systems for the television. Hearing aids or cochlear implants can help some sufferers, but having implants requires surgeryScientists have developed several treatments, from drugs affecting the central nervous system to electrical treatments and behavioural therapies, but the success has been limited.The new drug works on a protein called Kv3 that helps form pores on the surface of nerve cells in the area of the brain connected with hearing. The views expressed in the contents above are those of our users and do not necessarily reflect the views of MailOnline. The extent of the hearing loss varies too, from a mild to a severe hearing loss where loud safety signals may not be heard. 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 the short self-assessment test provided here.
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.
A sensorineural hearing loss can be of any degree ñ mild, moderate, severe or profound.
While the overall volume of sound may be reduced, the clarity of sounds or voices is also affected.
While the ageing process is a major contributor to hearing loss, it is certainly not a condition reserved for the later stages of life. Not surprisingly, given the impact of noise, males are considerably more likely to have hearing loss than women, including being twice as likely to have a moderate to severe hearing loss.


This graph shown here illustrates the time it takes to cause permanent damage to your hearing when you're exposed to different levels of sound. If you think you may be experiencing hearing loss, take our online hearing test simulator or visit a hearing professional in your area for a comprehensive hearing evaluation. Starkey Hearing Technologies is the only privately held, American-owned company in the hearing industry.
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. However, there are many other types of injuries that occur in addition to those that occur from strictly physical accidents.
There is a 60 percent chance of construction workers losing their hearing if they are exposed to hazardous noise throughout their career. There may be one of two common reasons why construction workers do not use hearing equipment. When hearing protection does not prevent hazardous noise from reaching the ear, or fails to do so effectively, the worker may be unknowingly exposed to excessive noise. Finally, a lack of training about how to wear hearing protection can contribute to the risk of overexposure and hearing loss. Job sites where workers are exposed to, or must use or interact with, heavy machinery, jackhammers, sledgehammers, nail and bolt drivers, electrical saws, and constant noise from demolition pose the most serious risk.
Permanent hearing loss occurs over time when repeated overexposure is experienced by the worker.
This typically occurs because of an obstruction like earwax or a tumor is blocking sound from getting to the ear. Damage may occur to the inner ear or the nerves that are responsible for hearing (auditory nerves). Mild hearing loss is usually associated with the inability to hear soft sounds or difficulty understanding speech in noisy environments.
Workers who are continually exposed to loud noises benefit the most from this type of hearing protection. As workers get hearing protection without distortion or muffling, they feel less isolated on the job site. Workers must wear their passive hearing protection until they are clear of hazardous noise areas. Anything that exceeds that level is automatically reduced, thus preserving the wearer’s hearing through limiting and preventing overexposure. These provide the best hearing protection in environments where hazardous noise occurs, but where communication is still important, even critical.
This allows workers to communicate with each other without risking overexposure to hazardous noise levels in situations where they are spaced apart and cannot effectively communicate by other means.
There is no official cure for hearing loss, but there are some treatments which may improve hearing or augment it.
As of December 2012, there have been roughly 324,000 individuals worldwide who have had the procedure and received implants. Instead, it gives deaf or hard-of-hearing individuals useful representations of sounds in the environment. The technology requires that the patients still have basic functional hearing and that the ear drum assembly, inner, middle, and outer ear are structurally intact. Hearing aids or cochlear implants can help some sufferers, but having implants requires surgery and hearing aids can be uncomfortable, increase the risk of infections and, even then, interpreting speech remains a challenge for some.Tinnitus is the perception of sound in one or both ears when there is no obvious source. These pores allow potassium to enter the cells - the potassium is needed to help signals, such as hearing signals, pass between the nerve cells.Researchers say there is evidence that levels of Kv3 become damaged or decline with age. More commonly it is manifested as a difficulty with word understanding, particularly in the presence of background noise. The good news is that conductive hearing loss can often be medically treated, and in many cases, hearing can be completely restored.
Other symptoms may also be present, such as ear pain, drainage from the ears, or a feeling of pressure or a blockage. In more than 95% of cases involving sensorineural hearing loss, hearing aids or cochlear implants are the recommended course of treatment.


Studies have shown that exposure to noise is estimated to be a contributing factor in around 37% of cases of the condition and interestingly, around 50% of Australians with hearing loss are still of traditional working age (i.e. This is illustrated through mandatory provision of ear protection on work sites and within factories. But did you know that only five percent of hearing loss in adults can be improved medically or surgically? 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. Workers who reach the age of 50, and have been working in construction for at least several years prior, are the most likely to experience hearing loss. This is typically not associated with damage caused by overexposure to noise or sound on a construction site, but it must be ruled out by a physician. Moderate hearing loss occurs when workers are unable to hear soft and moderately loud sounds and have considerable difficulty understanding speech, especially background noises. If possible, the hearing protection device should be custom-fitted for the individual, and considerable time should be spent explaining the importance of always wearing hearing protection. Loud noises, even sudden loud noises, are reduced to comfortable levels, while low dB noises are not muted or attenuated.
Because it’s electronic, it should be inspected prior to each use to make sure that the power is on, or that the device is properly charged and functioning normally. While cochlear implants are an available technology, they are still relatively expensive and full hearing restoration is not guaranteed.
For these individuals, they must relearn how to hear after the procedure and full hearing restoration is never guaranteed.
A transmitter receives signals from the speech processor and then converts them into electrical impulses. The labyrinth system of the ear must also be normal or at least not so abnormal that hearing becomes physically impossible. The type of sound heard varies from buzzing to ringing or hissing and can vary in pitch.Although many people cope well with the symptoms, for around 1 per cent of the population it has a significant impact on their quality of life.
This may cause patients difficulty in understanding speech and may be linked to tinnitus, too.
Nevertheless, every day millions of Australians are exposing themselves to noise levels that will surely lead to long-term damage to their hearing, including the use of personal stereo systems.
The vast majority of Americans with hearing loss (95 percent) are treated with hearing aids. Those experiencing conductive hearing loss may sense a reduction in sound level or the ability to hear faint sounds. 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. The result is that the worker can carry on a conversation with another co-worker without the need for special communication equipment and without removing the protective gear, risking overexposure. A second option is a hearing aid, which does not restore lost hearing, but rather amplifies sound, making hearing easier. Patients must learn to associate the signal provided by an implant with sounds they remember. Finally, an electrode array collects and transmits the impulses from the stimulator to various regions of the auditory nerve.
Tom focuses his practice on product liability cases, including defective machinery, work equipment, automotive parts, medical drugs, and chemicals.
Studies at the Institute of Experimental Medicine in Prague show the drug, known as AUT00063, can improve hearing in older animals, while research at University College London and the University of Southern Illinois has found the drug can have a beneficial effect on tinnitus. 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. This may cause patients difficulty in understanding speech and may be linked to tinnitus, tooA  Now University College London Hospital and ten other hospitals in the UK are embarking on a clinical trial, recruiting around 150 patients, who will receive four daily pills, or a placebo, every day for four weeks.
