A hearing aid or hearing aid component for placement in an auditory canal and/or in or behind an auricle of a wearer is provided with a biofilm-inhibiting coating. This biofilm-inhibiting coating includes an inorganic condensate that is modified with organic groups on the basis of a coating composition, which includes a hydrolysate or pre-condensate of one or more hydrolysable compounds with at least one non-hydrolysable substituent, whereby at least one portion of the organic groups of the condensate includes fluorine atoms and/or copper or silver colloids contained in the coating.
