Ear muffs are a type of personal protective equipment (PPE) designed to protect the wearer’s ears from loud noises. They consist of a headband that holds two cups, usually made of foam or other sound-absorbing material, over the ears. Ear muffs are typically worn in environments where loud noises are present, such as construction sites, manufacturing facilities, or airports, to protect against hearing damage. Some ear muffs are also designed for use in recreational activities, such as shooting sports or motorsports.
In terms of specifications, ear muffs can vary in terms of their noise reduction rating (NRR), which is a measure of how effectively they block out noise. The higher the NRR, the more noise they are able to reduce. Ear muffs may also differ in terms of their size, comfort, and adjustability. Some may have features such as a padded headband or a foldable design for easy storage.
