Abstract: A method and appertaining system implement the use of manufacturing protocols for hearing aid design such that the ability to build an instrument can be displayed as a numeric parameter based on the partial numerical and metrological contributions of all the essential parameters of the given impression, and a buildability index can be displayed as a 3D virtual image of the proposed shell or preferred shell types. The method utilizes a predefined parameter table comprising parameters to utilize for a buildability determination. The buildability index is computed based on impression shape data, selected shell type, selected number of device options, data obtained from the parameter table, and data obtained from a receiver table, and the buildability index is output to a display of a user interface device or an external system.

Abstract: A method and apparatus for setting a characteristic of a source hearing device on target hearing device are provided. A transformation database is created. A source hearing device including the setting of the source hearing device are identified, the characteristic of setting is to be set on the target hearing device. The setting which, according to the transformation database on the target hearing device, results in the characteristic corresponding to the characteristic of the identified source hearing device is recalled. The target hearing device is set using the recalled setting. Settings are stored in the transformation database during their creation, which have to be set to hearing devices of different types to be set in order to grant these hearing devices the characteristic of other identified hearing with identified settings.

Abstract: 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.

Abstract: To assist in the standardization of communication protocols and individual register models of various hearing devices, the register in the DSP/ASIC of a hearing device has a standardized interface in the DSP/ASIC. An application-specific, universal, generic command set that is transferred via the communication interface can be used therewith. Thus command set can be standardized over hearing device families, IC generations and across manufacturers, such that a universal software for adaptation of hearing devices can be achieved.
