ABSTRACT:
An acoustical hearing device is presented, including a foam and at least one porous component which is mechanically bonded to the foam. The mechanical bonding of the porous component arises during manufacture, wherein the porous component is placed into a mold cavity as an insert and a foam is formed within the mold so as to allow controlled penetration of the porous component during foaming. Importantly, entrapped air in the closed cavity may pass through the porous component during manufacture, thereby allowing the porous component to act as a mold vent. A method of manufacture of the hearing protective device of the present invention is also presented.
