1. A method of hearing aid fabrication comprising:

  • generating a simulated ear mold from a computer simulation of scanned ear mold data of an ear mold;

    trimming the simulated ear mold using software tools to generate a simulated hearing aid body;

    identifying at least one annular inflation groove on an outer surface of the simulated hearing aid body using the software tools;

    modifying the simulated hearing aid body to include the identified at least one annular inflation groove on the outer surface, to form a modified simulated body; and

    fabricating a hearing aid body from the modified simulated body.
