1. A method for computer-controlled production of otoplasties or adaptive earpieces comprising at least one part which is individually matched to contours of an auditory canal, said method comprising the steps of:

  • tracing of the contours of the auditory canal to obtain contour data, digitization of the contour data and storage of the digitized values;

    converting the digitized values into a multi-dimensional computer model of the external contours of the otoplasty or adaptive earpiece; and

    automatically or interactively selecting the components/functions for the interior of the computer model while simultaneously defining the wall thickness and optimizing the positions of the components/functions with respect to optimum function, position and minimum bulk.
