What is required if personnel work in a designated noise hazard area averaging more than 84 dB?

When personnel are working in a designated noise hazard area where noise levels average more than 84 decibels (dB), specific precautions must be taken to protect their hearing. The primary concern in environments with such high noise levels is the risk of hearing loss or damage, which can occur over time with prolonged exposure to intense sound.

Hearing protection is essential in these situations, as it helps mitigate the harmful effects of loud noises. This protection can come in various forms, such as earplugs or earmuffs, which are designed to reduce the intensity of sound that reaches the inner ear. Regulations and safety standards often require that workers in these environments utilize hearing protection to ensure their safety and long-term auditory health.

Other options like protective eyewear, respirators, and body armor are not specifically aimed at addressing the risks associated with noise exposure. While they are crucial in other contexts, they do not pertain to the hazards imposed by high noise levels. Thus, it is hearing protection that is explicitly required in this scenario.
