  • Calibration device and auditory prosthesis having calibration information
    Patent number: 4992966
    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.
    Type: Grant
    Filed: May 10, 1988
    Date of Patent: February 12, 1991
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Gregory P. Widin, Stephan E. Mangold, Mats B. Dotevall
  • Method and apparatus for determining acoustic parameters of an auditory prosthesis using software model
    Patent number: 4953112
    Abstract: A software model of the auditory characteristics of an auditory prosthesis is stored independently of the actual auditory prosthesis being fitted to determine the acoustic parameters to be utilized. A transfer function of the auditory characterictics of the individual auditory prosthesis to be fitted, or of an exemplary model of such an auditory prosthesis, is created, transformed into a table, or other usable form, and stored in software usable by the automated fitting program. The automated fitting program may then "test" or try by iterative process, the various settings for the acoustic parameters of the auditory prosthesis and determine accurately the results without actual resort the physical auditory prosthesis itself.
