1. A method for adapting an otoplastic of a hearing aid, the method comprising:
providing a flexible outer shell formed of a curable and not-yet-cured material, the flexible outer shell forming an outer wall of the otoplastic and defining a housing interior, wherein the housing interior is configured for accommodating electrical components;
sealing the housing interior at a proximal end thereof facing toward an eardrum in an intended worn state in an auditory canal of a hearing aid wearer and also sealing the housing interior at a distal end, opposite the proximal end, and installing a terminus plate at the distal end facing an auditory canal outlet side, and installing a loudspeaker at the proximal end on an eardrum side, on or in corresponding openings of the outer shell;
connecting the housing interior via a pressure inlet opening to a pressure and curing facilitator;
inserting the outer shell into the auditory canal of the hearing aid wearer;
applying an elevated internal pressure value to the housing interior via the pressure and curing facilitator, to press the outer shell against a wall of the auditory canal; and
initiating curing of the curable material via the pressure and curing facilitator while maintaining the internal pressure value.
