A hearing protector comprises a generally U-shaped spring headband to each of the opposed end portions of which there is affixed an inwardly projecting ear canal obturating pod of a size and shape adapted for partial insertion into the ear canal. Each pod comprises a soft compliant, smooth and hollow capsular element which is articulatingly affixed to its respective end portion of the headband. By this construction the ear pods through the biasing action of the spring headband, are partially urged into the ear canals in obturating relationship therewith. <IMAGE> |
