What does the term "permissible exposure limit" (PEL) refer to?

The term "permissible exposure limit" (PEL) specifically refers to the maximum allowable noise level to which a worker can be exposed without requiring the use of hearing protection. This limit is established to protect workers' hearing from noise-induced damage over time. When noise levels exceed the PEL, it indicates that the risk of hearing loss increases significantly, and protective measures, such as the use of hearing protection devices, must be implemented to ensure the safety and health of employees in noise-polluted environments.

Understanding this definition is crucial because it helps employers and employees recognize the importance of maintaining noise levels within safe limits to prevent occupational hearing loss. This concept is essential in the development and implementation of effective hearing conservation programs.
