SAFETY | Hearing Protection
Exposure to excessive noise at work is damaging 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 into 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 noisereducing
capacity, as established by the Environmental Protection Agency (EPA).
Howard Leight QM24+® Muff
Ultra-lightweight at only 6 ounces for prolonged usage. Newly designed for
even higher attenuation, the three-position muff with adjustable cup height and
