1. A microphone adapted to be worn in contact with the head of a wearer to pick up the speech of the wearer and to severely attenuate ambient sounds, consisting of an inertial reaction transducer, an acoustical enclosure, support means for said transducer, and an acoustical labyrinth, the support means for said transducer including relatively thin compliant suspension means made from rubber-like elastomer material, the support means including a protuberance normally extending outward from the plane of the suspension means but adapted to be deflected inwardly of the acoustical enclosure when said microphone is applied to the head of a wearer, said acoustical labyrinth constituting acoustical filter means for excluding at least high frequency ambient sound.
