ABSTRACT:
A hearing protection device readily insertable and removable from temple arms of eye glasses of varying size, width, angles and flanges, comprising a stiff but bendable vinyl tube, a connector cord, and an earplug. The tube is positioned around the temple bar of glasses past where the temple bar comes into contact with the user's ear when the glasses are worn. The device is held in position by pressure points of contact between the internal surface of the tube and points along the arm of glasses. Once mounted, and glasses worn, the sensation of the vinyl tube simulates the eyeglass arms themselves, and the earplug is conveniently positioned behind and outside of the user's line of vision. The earplug may be inserted and removed from the user's ears as desired given changing noise levels in the user's environment.
