Earmuffs

From Wikipedia, the free encyclopedia

(Redirected from Ear defender)

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 1984.

Earmuffs or muffs is a name sometimes lightly given to headphones.

Earmuffs is a form of sexual slang referring to the legs being pressed against both ears, implying oral sex.
