Double hearing protection device
First Claim
1. A double hearing protection device comprising:
- a circumaural hearing protector, wherein the circumaural hearing protector comprises an earcup adapted for covering a pinna of a user, and wherein the earcup comprises an interior attachment point;
an earplug device adapted for manual insertion into an ear canal of a user;
a tether assembly, wherein the tether assembly comprises an earplug termination and an earcup termination, and wherein the tether assembly is adapted for;
attaching to the earplug device at the earplug termination;
removably attaching to the interior attachment point of the earcup at the earcup termination; and
retracting for storage inside the earcup when the earcup is placed over the earplug device and over the pinna of the user.

Abstract
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.
