Abstract
Abstract A calibration device for an auditory prosthesis, such as a hearing aid, and an auditory prosthesis which contains such a calibration device. The calibration device comprises memory in which is stored information which is characteristic of information intrinsic to the invididual auditory prosthesis, the information being either information which represents a sufficient set of adjustment parameters required to calculate the transfer function of the auditory prosthesis or manufcturing information and a mechanism by which this information may be utilized by the auditory prosthesis or by the programming system of such auditory prosthesis.
