2118934 9304603 PCTABS00020 A helmet (10) for use with a bicycle, motorcycle or other vehicle. In one embodiment, a duct (40) is located at each side of the helmet (10), and used for the dual functions of drawing air from the interior of the helmet (10) and channeling ambient sounds (66) inside the helmet where the sounds can be heard by a user. Sounds may be enhanced by the use of microphones (106), speakers (118), and other electronic equipment. The side ducts (40) extend to the rear of the helmet and help to reduce drag and turbulence-induced vibration due to air flow. In another embodiment, separate air and sound ducts (80, 82) are located at each side of the helmet (10). Breakaway joints (131) may be used for the helmet (10). The breakaway joints (131) provide increased protection for a user because the joints (131) will break apart when the helmet (10) is subjected to excessive forces, causing the air and sound ducts to break apart and separate from the rest of the helmet.
