Abstract: A manually, selectively attenuating earplug button is disclosed, for insertion into a cavity of an earplug of a hearing protection device. The earplug button comprises a nested configuration of a first housing member (including a first opening to receive sound from an ambient environment) and a second housing member, surrounding the first housing member and including a second opening to output at least a portion of the sound passing through an audio channel located between said first and second openings. The first and second housing members include sidewall apertures for permitting a wearer to manually adjust the amount of sound admitted to the wear's ear from said ambient environment by rotating the first housing member (and thus its sidewall aperture) with respect to the second housing member.

Abstract: A manually, selectively attenuating earplug button, for insertion into a cavity of an earplug of a hearing protection device, is provided which includes a longitudinal central axis; a first opening to receive sound from an ambient environment; a second opening to output at least a portion of said sound; and an audio channel located between said first and second openings, said audio channel having a sound attenuation valve for permitting a wearer to manually adjust the amount of sound admitted to the wear's ear from said ambient environment. Also provided is a hearing protection device, including an earplug made of a soft resilient material having a hardness on the Shore A Durometer hardness scale, and an earplug button which is manually controllable by the wearer and capable of providing a plurality of sound attenuation settings, said earplug button disposed at least partially within a cavity of said earplug.
