This invention is directed to the elimination of the cause of hearing aid wind noise pollution which is referred to here as that form of audible vibrations generated by the energy of wind-produced vortices and eddy currents at the ear area and amplified by the hearing aid circuitry in the form of objectionable roar or burbles. Said invention constitutes a disposable porous blanket accessory provided for covering the obstructions and irregularities of the hearing aids in their operating mode and any pertinent outer ear area to prevent the formation of audible wind eddies, vortices, and burbles in the airstream. Said blanket is press-applied by use of an adhesive backing which is so affixed on the blanket surface as to preserve the porous nature of the blanket and its acoustic and electronic compatibility properties by either coating or impregnating only the individual fibers of the blanket surface to be so treated and thus retaining said properties.
