According to a Canadian study including 400 workers aged 38-65 years one in two boilermakers, shipbuilders and blacksmiths suffer from hearing loss, making them the group most at risk among construction workers. The Swedish construction industry's work environment council points out that the noise level at construction sites has increased because of heavier reliance on machines and power tools and faster completion of projects. The high frequency of hearing loss among construction workers illustrates the dire need for consistent and conscientious use of hearing protection.
In addition to hearing loss, noise in the workplace also is the cause of ringing or buzzing in the ears of 30-40 percent of the Canadian construction workers at the end of the workday.

However, whenever workers are exposed to some of those sounds for hours on end every day, hearing loss can become a serious problem. Approximately 22 million Americans are exposed to noise levels loud enough to damage hearing every year, according to the National Institute for Occupational Safety and Health.
In fact, 4 million workers go to work each day with damaging noise, and 10 million people in the U.S. For safety, NIOSH recommends that workers should not be exposed to noise levels that amount to more than 85 decibels for eight hours.
The organization put together a Noise Meter to help show how many decibels certain pieces of equipment put out. For instance, a chainsaw has a sound intensity of 110 dB, and without proper personal protective equipment, running a chainsaw for two minutes can be dangerous to the human ear. Reducing the long-term costs of audiometric testing, personal protective equipment and workers compensation. Helping companies comply with the Occupational Safety and Health Administration and other noise regulation requirements. The pocket guide goes into detail talking about hearing loss, how it happens and how to prevent it.
According to NIOSH, noise-induced hearing loss can’t be reversed, but it is 100 percent preventable. This article was written by Patty Vaughan, Online Managing Editor for Total Landscape Care. For the last 17 years, I've traveled to over 40 countries, and every continent, as an audiologist conducting presentations and training on audiology and hearing instruments for a major manufacturer.


World War I was an extremely bloody war that engulfed Europe from 1914 to 1918, with huge losses of life and little ground lost or won.
In the late summer of 1914, German and French commanders both anticipated a strategy that would involve large troop movements, as each side sought to gain  or defend territory. During trench warfare, opposing armies conducted battle at close range from a series of ditches dug into the ground.  This occurred when two armies faced a stalemate, with neither side able to advance and overtake the other. To set up a good trench, another said, “Select a flat 10-acre plowed field, so sited that all the surface water of the surrounding country drains into it.
The intensity of World War I trench warfare was such that about 10% of the fighting soldiers were killed.  Medical services were primitive and antibiotics had not yet been discovered.
On any day it was noisy in the trenches, but on a heavy combat day it, the noise was deafening.
It is easy looking back to criticize the WWI commanders for not emphasizing the use of hearing protection devices. As many as 95 percent of construction workers are exposed to high levels of noise on a daily basis. Among plumbers and pipe fitters, more than one in three (38 percent) suffer from work related hearing loss.
According to Swedish data, more and more people working in construction report hearing loss caused by noise. Tighter time schedules demand that several tasks are performed simultaneously, exposing the workers to more sources of noise at a time. According to the Canadian study, the hearing ability of workers using hearing protection is likely to be better over time than the hearing ability of their colleagues who do not protect their hearing.
The only condition is that you provide a direct link to the specific article you use on the page where you quote us. Conservative estimates provide $100 per dBA of savings when purchasing the quieter product. This savings is applicable across a wide variety of machinery and equipment. I've learned that audiologists the world over, while a diverse group, share the same goals and objectives for our patients. While the Germans initially swept through parts of Belgium and northeastern France, Allied forces pushed them back in the First Battle of the Marne (September 1914). Relatively minor injuries could prove fatal because of the onset of infection and gangrene. WWI saw the first use of magazine and belt-fed weapons using metal cartridges filled with smokeless-powder, which greatly increased the energy and noise of the gases exiting the muzzle.
From 1997 to 2001, the number of reported incidents of hearing loss increased from 115 per 1.000 to 177, a 36 percent increase in just four years.


I invite guest articles on topics ranging from differences in training, expertise, and scope of practice from one country to another to interesting, debonair, or disgusting practices.
Events quickly escalated as Kaiser Wilhelm of Germany urged Austria to declare war on Serbia.
In each bay of the trench we constructed fire-steps about two feet higher than the bottom of the trench, which enabled us to stand head and shoulders above the parapet.
The Germans recorded that 15% of leg wounds and 25% of arm wounds resulted in death, mainly through infection. High explosive replaced black-powder and there was a dramatic increase in the numbers with hearing damage.
Somewhere between 72 percent and 88 percent of them always or usually wear hearing protection. Stories of travel, clinical practice, research, training diversity and other topics are of particular interest. The Allies (France and Britain, at this point in the war) responded in kind and two long trenches were dug from the coast of France to Switzerland, which came to be known as the Western Front. During the day we were working in reliefs, and we would snatch an hour’s sleep, when we could, on a wet and muddy fire-step, wet through to the skin ourselves. The Americans (who did not enter the war until 1917) recorded 44% of casualties who developed gangrene died.
In the French Army the wartime prevalence of pensionable ear disabilities was 10%-20%, almost all due to NIHL. France and Britain then mobilized against Germany.  Such was the situation in July 1914 at the beginning of WWI. The trenches mostly ran alongside each other, separated by as much as one kilometer to as little as 15 meters apart.  By October 1914, neither army could advance its position, mainly because this conflict was being waged very differently from how wars had been fought in the 19th century. However, in England, the Oxford War Primers dismissed soldiers who reported hearing loss as malingerers who were exaggerating.
Forward-moving strategies such as head-on infantry attacks were no longer effective or feasible against modern weaponry like machine guns and heavy artillery; this inability to move forward created the stalemate. After the war Major T Jefferson Faulder RAMC reported hearing deficit from gunfire to be temporary.
