A selective attenuating earplug is provided. In an exemplary embodiment, a selective attenuating earplug includes a switch adjustable between a first position and a second position, and the switch includes at least one cantilever spring arm.

A lanyard is provided. The lanyard may include a lanyard cord which is attached to a personal item such as safety glasses or an access card, an earplug cord which is attached to a first earplug and a second earplug, and a flexible retractable sheath. The lanyard cord and earplug cord may be disposed in the lumen of the retractable sheath and the retractable sheath is movable between a first position where it covers a first section of the lanyard cord and the earplug cord and a second position where it exposes the first section of the lanyard cord and the earplug cord.

An external ear canal pressure regulation device including a fluid flow generator and an earpiece having a first axial earpiece conduit fluidicly coupled to the fluid flow generator, whereby the earpiece has a compliant earpiece external surface configured to sealably engage an external ear canal as a barrier between an external ear canal pressure and an ambient pressure.

An external ear canal pressure regulation device including a fluid flow generator and an earpiece having a first axial earpiece conduit fluidicly coupled to the fluid flow generator, whereby the earpiece has a compliant earpiece external surface configured to sealably engage an external ear canal as a barrier between an external ear canal pressure and an ambient pressure.

An earplug for blocking sound and method of making the same, which includes a planar insert within an earplug of compressible slow recovery foam. A method of attenuating sound by inserting the earplug at an ear canal entry so that the planar insert is tactilely vertical, and pushing the earplug into the ear canal allowing the earplug to flex perpendicular to plana surfaces of the planar insert.

An external ear canal pressure regulation device including a fluid flow generator, an earpiece having an axial earpiece bore, and a valved conduit fluidicly coupled to the fluid flow generator and the axial earpiece bore, whereby the earpiece has a compliant earpiece external surface configured to sealably engage an external ear canal as a barrier between an external ear canal pressure and an ambient pressure.

Occlusion devices, earpiece devices and methods of occluding an ear canal are provided. An occlusion device includes an insertion element, a foldable element and an expandable element. The foldable element is disposed on the insertion element and is configured to receive a medium via the insertion element. The expandable element is disposed over the foldable element. The foldable element is configured to unfold, responsive to the medium, and cause the expandable element to expand to contact the ear canal.
