Definitions

  • the invention relates to methods and computer program products for installing a new version of a hearing-device fitting-software package on a computer system.
  • Hearing- device fitting-software is used by hearing device professionals for adjusting hearing devices.
  • a device Under a hearing device, a device is understood, which is worn in or adjacent to an individual's ear with the object to improve the individual's acoustical perception. Such improvement may also be barring acoustic signals from being perceived in the sense of hearing protection for the individual. If the hearing device is tailored so as to improve the perception of a hearing impaired individual towards hearing perception of a "standard" individual, then we speak of a hearing-aid device. With respect to the application area, a hearing device may be applied behind the ear, in the ear, completely in the ear canal or may be implanted. Background of the Invention
  • a hearing-device fitting-software package is typically deployed by deploying a number of CD-ROMs on which an installation-software package is stored, or by downloading an equivalent installation-software package from the internet .
