A computerized method is provided for designing a vent in a hearing aid housing shell based on an image of a patient's ear canal impression, and wherein a program is provided on a computer-readable medium. With the program, an image of a starter housing shell based on the image of the patient's ear canal impression is created which is longer than a final version of the housing shell to be created. A starter vent running from an inner canal end near the patient's ear drum to an outer end of the starter housing shell is placed inside the shell. Components are then placed substantially as deep as possible inside the starter shell but lying outside of the starter vent. Portions of the starter shell lying beyond where a faceplate is to be mounted are removed and the faceplate is mounted. The starter vent is then grown larger so that it fills substantially all space inside the shell without interfering with the components.

Method of generating an optimized venting channel in a hearing instrument

A method for designing a prosthetic device includes acquiring a three-dimensional image of an anatomical surface. A rules script for automatically performing a plurality of image processing rules using a script interpreter is executed. For each particular rule of the plurality of rules, one or more anatomical features that are relevant to the particular rule using a surface shaping engine are determined, the one or more determined anatomical features are automatically segmented from the acquired three-dimensional image using a feature detector, and the particular image processing rule is performed on the acquired three-dimensional image based on the automatically segmented anatomical features using a CAD tool. A prosthetic device design is produced based on the three-dimensional image upon which the rules of the plurality of image processing rules have been performed.

A method and appertaining system provide for automatically adding a wax guard to a hearing aid shell impression. The location of a canal, tip of the canal, and central line of the impression are automatically identified in a digital 3D representation of a hearing aid shell impression. A first wax guard plane is determined at a predefined flip distance from the canal tip along the central line, and a second wax guard plane is determined at a predefined canal tip offset distance from the canal tip along the central line. A size and position for a feature of the wax guard is calculated based on predefined parameters, and the wax guard is constructed utilizing the calculated side and position. The type of wax guard can be a bell bore design, an open design, a Philip design, or a flip design.

A system and appertaining algorithm provide a cutting and shaping of the hearing aid shell using an Ellipsoidal Line Cut that increases the speed of detailing operations and enables a creation of more cosmetically appealing shells. A contour algorithm determines a projected contour on the bottom cut plane that corresponds in shape to a portion of the line cut plane contour, and a merger algorithm defines a line cut surface between the portion of the line cut plane contour and the projected contour. An elimination algorithm eliminates parts of the new hearing aid shell design that extend beyond boundaries defined by the original hearing aid shell design.
