ABSTRACT A hearing aid having a stereophonic microphone mounted on a flexible base and means for adhering it to the top of the head. This substantially eliminates the shadow effect encountered when two separate hearing aids are used, one for each ear, which reduces the ability of the wearer to locate the source of sounds originating at an angle from a vertical central plane passing through the nose and axis of the wearer.
