An acoustic earmuff device is provided comprising a rigid cup, including inner and outer surfaces, a sound channel means disposed through said cup shaped portion, and a plate means operatively associated with said sound channel means, such that when the plate means is in a first orientation, sound attenuation through the plate means is greater than when the plate means is in a second orientation.

The present invention provides an earmuff device comprising an earmuff cup having at least a window portion which is formed of an optical material which transmits light rays in such a way that the human eye can see through the material to a degree that an earplug or other object inserted within the ear is visually perceivable to the human eye. In other words, the earmuff cup is formed of a transparent material or a translucent material so long as the earplug inserted within the wearer's ear is visually perceivable through the translucent portion of the earmuff cup. Because the earmuff cup is formed of a material that permits an individual, such as a supervisor or hearing conservationist, to perceive whether an earplug is inserted within the wearer's ear, the earmuff device of the present invention is particularly well suited for use in a dual hearing protection environment in which the previous method of compliance monitoring was time consuming and difficult.

Hearing protective devices having glow-in-the-dark properties are presented in the present invention. In an exemplary embodiment, the hearing protective device comprises a semi-aural device, an earplug, or an earmuff device. In all embodiments, a glow-in-the-dark material is incorporated into at least a part of the hearing protective device so that the glow-in-the-dark material continues to emit light for an extended period of time in a dark environment after the material has been excited by irradiation. Preferred and exemplary glow-in-the-dark materials comprise phosphorescent materials. The glow-in-the-dark materials may be disposed on a surface of the hearing protective part or dispersed throughout the material which forms this part.
