High-noise levels can damage our hearing, that is an indisputable fact due to medical research, but it also can lead to hearing loss and tinnitus. Now imagine a loud work place with noises from equipment, machines along with other heavy machinery blaring at full blast, every single day. Conditions like these are not only uncomfortable, if you are not wearing the proper hearing protection equipment, and can certainly increases your chances of experiencing hearing loss and tinnitus. In line with the U.S. Department of Labor, roughly 30 million Americans are exposed to harmful noise due to workplace conditions or environment.
Of course, the danger of hearing loss and tinnitus also considerably increases. That’s why the Occupational Safety and Health Administration (OSHA), has generated – and recently modified – instructions for disturbance levels on the job.
The decibel amount allowed under OSHA for an eight-hour time cannot exceed 90 dB; for six hours, the restriction is 92; for four hours, the most is 95 decibels; for several hours, 97 decibels; for two hours, 100 decibels; for one-and-one-half hours, 102; for one hour, 105. The duration of every period must be blended to determine the optimum noise exposure once the everyday noise exposure stretches over several periods in certain evening.
For businesses who follow the National Institute on Occupational Safety and Health (NIOSH) tips, they are helping and protecting their workers beyond what OSHA recommends. NIOSH proposes for any disturbance over 85 decibels is harmful and protection should not be unworn. As an example, exposure to a-sound hitting 85 decibels is protected for only 8 hours; a sound achieving 86 decibels is not dangerous for 6 hours. For ninety decibels, 31 minutes and 2 hours could be the save hearing period.
There is a sizable disparity while OSHA and NIOSH requirements are compared. However OSHA is often adopted and this continues to be the standard up to now. However, as recently as October 2010, OSHA released its goal of altering its formal meaning of office noise exposure standards, requiring employers to get methods that were more effective to safeguard their employees’ hearing.
