When should hearing protection be used?

Hearing protection should be used when noise levels exceed 85 decibels, as this is the threshold established by regulatory guidelines to protect workers from hearing damage. Prolonged exposure to sound levels at or above this limit can lead to noise-induced hearing loss, which is a significant occupational hazard in many industries. Therefore, monitoring noise levels and providing appropriate hearing protection is essential in maintaining workplace safety and protecting employees' auditory health.

In contrast, using hearing protection at all times in the workplace could be impractical, as it may not be necessary in areas where noise levels are within safe limits. Restricting its use to only during machine operation might leave workers unprotected during other noisy activities that could occur. Additionally, wearing hearing protection when working near quiet areas wouldn't address the risk of exposure to hazardous noise in louder job areas, which is why context and awareness of specific noise levels are crucial for effective hearing conservation measures.
