Abstract
An industrial hearing protection and communication assembly including a frame having a front frame member that, includes a substantially transparent shatterproof eye panel disposed to shield a wearer's eyes, and at least one protective ear insert structured to be fitted into a wearer's ear in order to substantially muffle exterior noise. A speaker head audibly communicates an audio signal received by a receiver disposed on the frame and is structured to be inserted into a bore defined in the protective ear insert, and thereby, into one of the wearer's ears. The audio signal is audible to the wearer while the exterior noise is muffled by the protective ear insert and the speaker head is shielded from perspiration or other body contaminants of the wearer. Further, the protective insert can be variably positionable in accordance with the location of the wearer's ears.
