Abstract
An earplug device includes a headband with earplugs attached to the ends thereof. The earplugs have a head portion and a shank portion, the latter with its rear end joined to the associated headband end. The shank portion has a stiffened middle section and is articulately connected on either side thereof respectively to the head portion and headband end to form a doubly articulated shank configuration. The head portion is thus given the opportunity of coacting in the best possible way with the auditory canal of an ear, and to a substantial degree independently of the attitude of the headband.
