A protective cap assembly for a CIC hearing aid (20) comprises a perforated cap (90) mounted over the lateral end of the hearing aid to protect the hearing aid from contaminants. At least a portion of the cap (90) includes a protective coating and a plurality of perforations. The placement and size of the perforations can be configured to provide sufficient aeration and drainage to reduce a relative humidity of the cap interior when the hearing aid is positioned in the ear canal (10). The perforations also operate as sound conduction channels for conducting sound to the cap interior.
