Every day, we experience sound in our environment, such as the sounds from television and radio, household appliances, and traffic. Normally, we hear these sounds at safe levels that do not affect our hearing. However, when we are exposed to harmful noise—sounds that are too loud or loud sounds that last a long time—sensitive structures in our inner ear can be damaged, causing noise-induced hearing loss (NIHL).
Today, the introduction of calibration and docking stations has provided gas detector users the tools needed to further simplify the calibration process. Here are three questions to consider in choosing equipment to calibrate your instruments.
At a Tuesday session at the 2013 NSC Congress & Expo, former Treasury Secretary Paul O’Neill, OSHA boss Dr. David Michaels, and NIOSH director Dr. John Howard discussed the “future of safety.” Who’s to say what the future holds, right? And predictions about the future are soon forgotten. Here are some of ISHN’s predictions for the future of safety:
Hearing loss happens for many reasons. Some people lose their hearing slowly as they age. This condition is known as presbycusis (prez-buh-KYOO-sis). Doctors do not know why presbycusis happens, but it seems to run in families.
In week 2 of the NFL season, fans at CenturyLink Field in Seattle broke the Guinness World Record for the highest peak decibel level — 136.6 decibels — ever recorded at a stadium.
OSHA is urging workers, residents and businesses engaged in flood cleanup in Colorado to protect themselves against hazards as cleanup efforts continue and rebuilding activities begin.
After a decade of war, America is well schooled on post-traumatic stress, lost limbs and traumatic brain injury, but the most common injury sustained by U.S. troops is literally a silent wound: hearing loss, according to NBC News.
A recent study claims that more than eight in 10 New Yorkers are exposed to enough noise to damage their hearing. Richard Neitzel, Ph.D., an environmental health sciences researcher at the University of Michigan in Ann Arbor, and colleagues say that city dwellers may be particularly at risk for noise-induced hearing loss (NIHL) because they are exposed to high levels of noise throughout the day.
