DOUBLE HEARING PROTECTION DEVICE

摘要

A double hearing protection system is disclosed. The earplug portion of the system contains a tether attachment mechanism that may be selectively attached to the interior of a circumaural hearing protector designed with the mating attachment. The tether retracts into the earcup when both the earplug and circumaural hearing protector are worn, ensuring that the earseal against the head is not broken by the retractable tether. The attachment point inside the ear cup mates to the end of the tether in a way that prevents foreign object damage in dangerous work environments, and limits the vibratory path from the earcup to the earplug through a flexible attachment mechanism. The benefit of both the earplug and earcup combined offers the double passive hearing protection for extreme noise environments while providing for a convenient means by which to achieve the double hearing protection and not compromise its performance through the attachment mechanism.
