ABSTRACT:
An earfoil (2) is used with a helmet (4) having a chin strap (6) which passes in front of the ear (30) and under the chin. The earfoil includes a wind deflecting, sound-permeable earfoil body (22) sized to cover the user's ear. The front edge (44) of the earfoil body is secured to the chin strap and lies against the user's head. The upper edge (46) of the earfoil body is secured to the lower circumferential edge (52) of the helmet just above the user's ear. These attachments are such that the earfoil body overlies the rear flange (56) of the user's ear while the rearward edge (62) of the earfoil body is spaced apart from the ear flange. This permits eddy current airflow to occur about the ear flange to enhance cooling even while the earfoil body directs airflow away from the concha (28) of the user's ear. The invention provides for a reduction in personally heard wind noise with enhanced eddy current cooling.
