Abstract

Abstract A sound-attenuating earcup assembly for isolating the ear of a wearer from ambient sound while affording the wearer external communication capability without doffing the earcup assembly in which a sound-attenuating earcup of relatively rigid material forms a sound-attenuating cavity having an opening for receiving the ear of the wearer. An earphone assembly is resiliently mounted in the opening and biased outwardly of the cavity whereby the earphone assembly presses against the wearer's ear when the earcup assembly is in position on the wearer's head.
