titleOfInvention	Acoustical earmuff
abstract	An earmuff cushion providing improved attenuation is described. The cushion is a foam material having a low static stiffness, and a high dynamic stiffness, which produces improved attenuation in the earmuff in which it is used. Earmuffs made from the cushion and improved methods of making the cushion and the earmuffs are also described.
