Hearing Protection

Exposure to excessive noise at work is damaging to people's hearing.  Personal protective equipment (PPE) is available in two basic formats: ear muffs, which fit over the entire external ear and seal against the side of the head, and earplugs, which are inserted directly in to the ear canal.  Hearing protectors will always have an assigned Noise Reduction Rating (NRR), which indicates the adequacy of a hearing protector's attenuation, or noise-reducing capacity, as established by the Environmental Protection Agency (EPA).
