Earmuffs

By Kip Cullinan

Chester Greenwood

Chester Greenwood was born in Farmington, Maine in 1858. He invented the earmuffs when he was just 15. He invented them because he was mad at the cold when he was testing out a new pair on ice skates. He ended up making a lot of money selling ear muffs but made a lot more selling them to the U.S. military as ear protectors in World War One. In 1937 Chester Greenwood died in Farmington, Maine. During 1977 Main declared December 21 "Chester Greenwood Day."

Earmuffs

Termal earmuffs keep your ears warm in the winter. Acoustic earmuffs have a cup lined with special material to block out loud noises. Acoustic earmuffs are used a lot at construction sites. Ear plugs can be used with earmuffs to make noises even softer. Ear defenders are made with acoustic foam to absorb sound waves.
