Abstract
Abstract A pair of motorcycle helmets worn by two riders on the same motorcycle are interconnected by a hollow, flexible tube, whose opposite ends are connected to an ear covering portion of each helmet. Each helmet also has a stiffer, speaking tube, having an end connected to the same helmet portion as the flexible tube, and an opposite end connected to a mouthpiece located just forwardly of the wearer''s mouth. Thus, the two helmet wearers can talk to each other through the tubes as well as hear themselves talk.
