Not everybody gets to work in a nice quiet office. Many people work in loud factories or on construction sites with constant booming and heavy machinery noise.
According to the Occupational Safety and Health Administration, nearly 30 million people are exposed to hazardous noise levels at work every year. Long term exposure to high levels of noise can cause permanent tinnitus or hearing loss. OSHA sets employee noise exposure limits at 90dBA for 8 hours a day, and only 2 hours of exposure to 100 dBA sound levels.
So if you experience hearing loss while working in a noisy environment, you may be eligible for workers' compensation.
