Which organization provides guidelines for permissible noise exposure levels in the workplace?

The organization that provides guidelines for permissible noise exposure levels in the workplace is OSHA, which stands for the Occupational Safety and Health Administration. OSHA is responsible for setting and enforcing standards that ensure safe working conditions for employees. In particular, OSHA has established permissible noise exposure levels as part of its regulations to prevent occupational noise-induced hearing loss. These regulations outline the maximum allowable noise levels over specific time periods, emphasizing the importance of protecting workers' hearing health in environments with potentially harmful noise levels.

While other organizations like NIOSH (National Institute for Occupational Safety and Health) and the CDC (Centers for Disease Control and Prevention) have roles in research and providing recommendations regarding workplace health and safety, OSHA is the primary authority that enforces regulations aimed directly at permissible exposure levels for noise in the workplace. The EPA (Environmental Protection Agency) focuses more on environmental noise issues rather than workplace-specific guidelines. Thus, OSHA is recognized as the definitive source for such regulations.
