Which organization sets guidelines for permissible noise exposure levels?

The organization that sets guidelines for permissible noise exposure levels is the Occupational Safety and Health Administration (OSHA). OSHA is responsible for establishing and enforcing workplace health and safety standards, including regulations related to noise exposure in occupational settings. These regulations help protect workers from the harmful effects of excessive noise, which can lead to hearing loss and other health issues.

OSHA's permissible exposure limits (PELs) serve as the benchmarks that employers must follow to ensure safe working environments. The guidelines provide clear standards on the allowable noise levels and the duration of exposure, which are critical for maintaining worker health.

Other organizations like the CDC, EPA, and NIOSH contribute important research and recommendations regarding health and safety, including studies on noise and its effects. However, OSHA is specifically tasked with the enforcement of regulations that directly affect workplace safety and permissible noise exposure levels.
