Earmuffs are objects designed to cover a person's ears for hearing protection or for warmth. They consist of a thermoplastic or metal head-band, that fits over the top or back of the head, and a cushion or cup at each end, to cover the external ears.
What should I know about the fit of my hearing protectors?
Follow manufacturer's instructions. With ear plugs, for example, the ear should be pulled outward and upward with the opposite hand to enlarge and straighten the ear canal, and insert the plug with clean hands.
Ensure the hearing protector tightly seals within the ear canal or against the side of the head. Hair and clothing should not be in the way.
