Abstract

Earmuffs with a joint are provided to create a biased pressure distribution about a perimeter of the cup. The earmuffs may include a pivot joint. The pressure distribution creates a wedging pressure (e.g., on a top edge) on the cups that hold the earmuffs on the user's head, for example, when the user rotates the headband behind the head. The bias pressure is also used to adjust the seal formed between the pad and the user's head. Adjustments to the moment created by separating the joints from the cup's apex enable a user to selectively adjust the seal according to the user's preference. A cam is added to the headband to change the hoop stress distributed at the joints and further adjust the compressive forces generated to hold the earmuffs against the user's head.
