  • Publication number: 20060138691
    Abstract: A hearing device including a foam, a foam insertable portion, a component, and a foam handle portion, and a method of forming the same. The component is nestable with and bondable with the foam such that the component is at least partially within the foam insertable portion and the foam handle portion. The hearing protective device includes earplugs attached to a flexible cord, under-the-chin element, or headband. A method of making a hearing protective device including disposing a component into a mold, introducing a foam or foamable mixture into the mold, causing the foam to rise such that the component is nested within and bonded with the foam.

  • Publication number: 20050274568
    Abstract: A hearing protection device insertable into an earcanal is provided, the device generally including a stem portion, a sound attenuating portion affixed to and extending at least partially over the stem portion, and a volume of space disposed between and delimited by the sound attenuating portion and the stem portion, where at least a part of the sound attenuating portion is collapsible into the volume of space during insertion of the hearing protection device into the earcanal.

  • Patent number: 6695093
    Abstract: The present invention provides an earplug formed of a body and a stem member. The body has an insertion end and an opposing second end and further includes a stem channel formed therein. The stem member is disposed within the stem channel of the body so, as to securely couple the stem member to the body for easy insertion of the earplug into an ear of the wearer. According to the present invention, the stem member is formed of a material such that insertion of the earplug into the ear results in the stiffness of the stem member decreasing such that the stem member becomes less stiff upon being inserted and positioned within the ear. Advantageously, the design and/or material of the stem member permits the earplug to be stiff for insertion thereof into the ear; however, the preferred material used to form the stem member exhibits a softening characteristic such that upon insertion into the ear, the stem member softens.

  • Patent number: 5113967
    Abstract: An earplug uses damping to render unimportant a Helmholtz resonance between the acoustic mass intrinsic to a sound channel thereof and the compliance of air in the earcanal, in combination with a readily manufacturable external structure coupled to the sound channel to increase response characteristics at higher frequencies in a predictable and well controlled manner in order to provide a highly desireable uniform frequency response.
