EARMUFFS

'Earmuffs' are objects designed to cover a person's ears for protection. They consist of a thermoplastic or metal head-band, that fits over the top of the head, and a pad at each end, to cover the external ears. They come in two basic kinds:

★ 'Thermal earmuffs:' the original type, worn in winter to keep a person's ears warm. They were invented by 15 year old Maine resident Chester Greenwood in 1873. He came up with the idea while his grandmother made the muffs.

★ 'Acoustic earmuffs', also known as 'ear defenders': cups lined with sound-deadening material, like thermal earmuffs and headphones in appearance, which are worn as hearing protection. These may be carried on a head-band or clipped onto the sides of a hard hat, for use on construction sites. Some manufacturers combine headphones with ear defenders, allowing the wearer to listen to a music, communication or other audio source and also enjoy protection or isolation from ambient noise. Acoustic earmuffs were created in Italy in 1982.
'Earmuffs' or 'muffs' is a name sometimes lightly given to headphones.
