ABSTRACT:
A portion of a mask or helmet covering a user's ear has an aperture covered by a sound-collecting and sound-transmissive protector swivelingly mounted thereon. The protector has a substantially parabolic reflector surface oriented substantially perpendicular to the protector's axis of rotation which magnifies sounds arriving from a particular angular direction and directs the sound through a plurality of holes axially penetrating through the protector from an outer to an inner surface. A user manipulable actuator nib extends axially outwardly from a peripheral portion of the outer surface of the protector allowing user control of swiveling movement.
