Personal protective equipment (PPE) is also an important way to reduce exposure to noise. PPE can include earplugs or earmuffs, which can protect workers from noise levels up to 115 dB. Although there are many ways to reduce exposure to noise on mine sites, the most effective way to protect workers is by using a combination of these methods.
